WebD. When calculating molar mass of a chemical compound, it states how many grams are in one mole of a substances. 27. ____ 2. The mass in grams of one mole of a substance is … WebFirst, you can calculate the molar mass of FeCl2 by adding the molar masses of Fe (55.845 g/mol) and 2 atoms of Cl (2 times (35.446 g/mol). This gives a molar mass of 126.737 g/mol. Since each mole is 126.737 grams, you multiply 3.5 mols by 126.737 grams, giving you 443.58 grams.
