Enter the chemical formula of a compound to calculate its molar mass and elemental composition:
To calculate molar mass of a chemical compound, please enter its chemical formula and click 'Calculate'.
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
The Adooq dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.
The Adooq 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
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=20 ml and V1 is the unknown:
The Adooq molarity calculator is a useful tool which allows you to calculate the:
The Adooq molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
We promise all products to perform as described.
