Grams of an element in a compound
WebJun 4, 2024 · Calculate the molar mass by multiplying the number of atoms of each element in the compound (its subscript) times the atomic mass of the element from the periodic table. Molar mass = (2 x 1.008) + (2 x 15.999) Molar mass = 34.014 grams/mol WebApr 30, 2024 · Numerically, this would be (2) (1.008) + (1) (16.00) = 18.016. This is the molar mass of the compound; it has units of grams per mole. Divide the mass of the compound in grams by the molar mass you just calculated. The answer is the number of moles of that mass of compound. For example, 25 grams of water equals 25/18.016 or …
