WebIf we have a chemical compound like NaCl, the molar mass will be equal to the molar mass of one atom of sodium plus the molar mass of one atom of chlorine. If we write this as a calculation, it looks like this: (1 atom x 23 grams/mole Na) + (1 atom x 35.5 grams/mole Cl) = 58.5 grams/mole NaCl 2. WebMay 20, 2024 · As usual, we start with the quantity we were given: 3.59molFe2O3 × ( 3molSO3 1molFe2O3) = 10.77molSO3 The mol Fe 2O 3 units cancel, leaving mol SO 3 unit. Now, we take this answer and convert it to grams of SO 3, using the molar mass of SO 3 as the conversion factor: 10.77molSO3 × (80.06gSO3 1molSO3) = 862 gSO3
