How do you find molar mass

WebFeb 2, 2024 · To determine the molar ratio from the molecular weight, you need the mass of each substance. Convert the molecular weight of the first substance into its molar mass. Divide the mass of the first substance by its molar mass to obtain the number of moles used (or produced) in the reaction. WebMass, molar concentration, volume, and formula weight are related to each other as follows: Mass (g) = Concentration (mol/L) * Volume (L) * Formula Weight (g/mol) What is mass? Mass (m) is the amount of matter present in a substance. The value is constant and, unlike weight, is not affected by gravity. What is formula weight?
