3.6: Formula Mass and Molar Mass of Compounds
WebThe molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms. Molar mass serves as a bridge between the mass of a material and the number of moles since it is not possible to measure the number of moles directly. Key Terms molar mass WebMass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol) An example of a molarity calculation using the Tocris molarity calculator 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?
