Converting from moles of a substance to mass of a substance requires simple multiplication. Multiply the moles of the substance by its molar mass from the periodic table will provide the solution. For example, if you want to know the mass of two moles of water, multiply two by water's molar mass, which is 18 grams. 18 * 2 = 36. So the mass of two moles of water is 36 g. This quiz will cover simple mole-mass conversions. You will need a periodic table and a calculator. Select the best answer from the choices.
