Notice that the units on molar mass are grams per mole (g/mol) this looks a lot like a conversion factor that relates two units: grams to moles just like there are 12 inches/1 foot, for al2(so4)3 there are 34217 g/mol this allows us to convert between grams of al2(so4)3 and moles of al2(so4)3 the following two example.

Stoichiometry tutorial using molar mass in calculations molar mass as a conversion factor chemical reactions occur on a molecular (or atomic) basis when we want to plan a chemical reaction, we must know the number of molecules (or atoms or formula units) of a compound that should be present in the flask.
Mole conversions practice gap-fill exercise fill in all the gaps, then press check to check your answers round molar masses to the nearest whole number when doing calculations you will need a periodic table give your answers as numbers, not words 1 what is the mass of 4 moles of helium, he grams. Quiz theme/title: mass-mole conversions description/instructions converting from mass of a substance to moles of a substance requires simple division dividing the mass of the substance by its molar mass from the periodic table will provide the solution for example, if you want to know the number of moles in 100. Molar mass conversion factors help for an introduction to chemistry by mark bishop. Stoichiometry expresses the quantitative relationship between reactants and products in a chemical equation stoichiometric coefficients in a balanced equation indicate molar ratios in that reaction stoichiometry allows us to predict certain values, such as the percent yield of a product or the molar mass of a gas.
