Amino Acids Converter FAQ

What is the sequence of amino acids in a protein?

You see, protein is built in a chainlike fashion, with amino acids as the links. So, if your DNA specifies that a protein should be made using the amino acid valine, then lysine, and finally serine, then those amino acids would be assembled in that sequence.

Molarity Calculator

The molarity calculator is a useful tool which allows you to calculate the:

  • mass of a compound required to prepare a solution of known volume and concentration
  • volume of solution required to dissolve a compound of known mass to a desired concentration
  • concentration of a solution resulting from a known mass of compound in a specific volume

Calculate now!

*When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / CoA (available online).


The molarity calculator equation

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)

  2. Enter 10 into the Concentration box and select the correct unit (millimolar)
  3. Enter 10 into the Volume box and select the correct unit (milliliter).
  4. Press calculate
  5. The answer of 19.713 mg appears in the Mass box

Molarity Calculator FAQ

What is a molarity calculator used for?

This molarity calculator is a tool for converting the mass concentration of any solution to molar concentration (or recalculating the grams per ml to moles). You can also calculate the mass of a substance needed to achieve a desired molarity.

What is the abbreviation for molarity?

Molarity has units of , which can be abbreviated as molar or (pronounced "molar" ). The molar concentration of the solute is sometimes abbreviated by putting square brackets around the chemical formula of the solute.

What is the difference between mass and molarity?

Mass is the mass of the solute (substance) in grams and volume is the total volume of the solution in liters. Molarity has many applications. One of them is to calculate the dilution of the solution. The unit of molarity is moles per cubic decimeter. They are labeled mol/dm³ and M (pronounced "molar").

How do you find the molarity of a solution?

(1) mol. = V*M. where V = the volume of solution and M = the molarity. The mass of solute can also be determined when a volume V is delivered by noting that the number of moles is equal to the mass, m, divided by the formula mass, FM.

What is molarity?

Molarity is the number of moles of solute per liter of solution. For example, if you dissolve table salt in water, salt is the solute, and water is the solution. One mole of sodium chloride weighs 58.44 grams. If you dissolve 58.44 grams of NaCl in one liter of water, you have a one molar solution, abbreviated as 1M. It is important to know, that the volume of solution is measured after the solute is dissolved, not before. Also, don’t confuse molarity with molality, which is slightly different!
When you see “1M”, you read that aloud as a “1 molar solution”.

Does anyone have some sort of resource that can explain to me what the actual hell are moles/molar calculations?

A mole can be considered to be a unit of measurement, just slightly harder to convert between.
You know that to go from grams to kilograms you multiply by a thousand, well to go from grams to moles you divide by the relative atomic/formula mass from the periodic table.
A mole, or avagadro's constant is just a number. It is the number of atoms of an element in a particular mass of that element and it was all based on carbon. So, in 12 grams of carbon there are 6x1023 atoms of carbon. In 14 grams of nitrogen there are 6x1023 atoms of nitrogen.
The reason we convert to moles is because one gram of hydrogen doesn't react with one gram of chlorine to make Hydrochloric Acid, but one atom of hydrogen does react with one atom of chlorine to make hydrogen chloride. When we convert to moles we are converting a known mass of an element into a number of atoms so we can use that number to do calculations relating to that reaction.
Typically in the GCSE you use moles to work out the empirical formula of a compound, that is the simplest whole number ratio of atoms of each element in a compound. Moles must be used because it's a ratio of atoms not a ratio of mass.

The dilution calculator equation

The dilution calculator is based on the following equation:

Concentration(start) x Volume(start) = Concentration(final) x Volume(final)
This equation is commonly abbreviated as: C1V1 = C2V2
An example of a dilution calculation using the dilution calculator

What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?

Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=10 ml and V1 is the unknown:

  1. Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
  2. Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
  3. Enter 20 into the Volume (final) box and select the correct unit (milliliter)
  4. Press calculate
  5. The answer of 100 microliter (0.1 ml) appears in the Volume (start) box

Dilution Calculator FAQ

What is the solution dilution calculator used for?

Meant to be used in both the teaching and research laboratory, this calculator (see below) can be utilized to perform dilution factor calculations when working with molar or percent (%) solutions. See our Molar Solution Concentration Calculator for a definition of molarity and molar solutions.

What is the Dilution of Solutions?

What is dilution? Dilution is the process of decreasing the concentration of solute in a solution by changing the amount of solvent. The dilute solution definition requires an understanding of basic mixture chemistry. A solution is a type of mixture where one substance, the solute, is dissolved in another substance, the solvent. Dilution chemistry is important for carrying out chemical reactions, manufacturing, biomedical research, and more. Solutions are even present in our everyday life. Salt water is an example of a solution where the solute is salt and the solvent is water.

What is the units of concentration?

Molar concentration c is the amount of substance in a certain volume of the substance. It is expressed in “mole” units (symbol: M), where 1 M = 1 mol/liter.
Mass concentration ρ is the amount of substance in grams in the given volume of a substance. Expressed in grams/liter.
If you want to determine the mass concentration of the solution, you must multiply the molar concentration by the molar mass of substance M (represents in kg / mol):$$ ρ = c * M $$

How to calculate dilution factor?

Before calculating the dilution factor, you need two values namely the original volume of the diluted solution and the final volume of the solution after dilution. You can also get the volume you’ve added to the solution to dilute it. In such a case, the value of the final volume is the original volume plus the value of the added volume.

How do you calculate the amount of solvent needed to dilute?

To help scientists calculate the appropriate amount of solvent to dilute a solution, there is a dilution formula. The dilution formula uses the concentration of the starting and ending solute in molarity, or moles per liter solution, and the total volume of the solution in liters. The formula is: M1 V1 = M2 V2
Where M1 is the molarity of the starting solution and V1 is the volume of the starting solution. The M2 is the molarity of the final solution and V2 is the volume of the ending solution.
