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 grams of sodium chloride, you must divide that number by sodium chloride's molar mass, which is 58.5g/mol. The answer is 1.7 moles. This quiz will cover simple mass-mole conversions. You will need a periodic table and a calculator. Select the best answer from the choices.
