WebApr 30, 2024 · In the case of water, multiply the atomic weight of hydrogen by two, and the atomic weight of oxygen by one, then add the products. Numerically, this would be (2) (1.008) + (1) (16.00) = 18.016. This is the … WebMay 21, 2024 · Multiply the resulting number by the number of grams per mole of product to find the mass of product able to be produced by the given amount of reactant. There are 2.1749 moles of NaCl and one mole equals 58.243 grams. 2.1749 × 58.243 = 126.67, so the 50.000 g of Na used in the reaction can create 126.67 g of NaCl.
