WebOct 15, 2024 · The mol Fe 2 O 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: (6.5.3) 10.77 m o l S O 3 × 80.06 g S O 3 1 m o l S O 3 = 862 g S O 3. Our final answer is expressed to three significant figures. WebLooking at the equation, 1 mol of Mg forms 1 mol of H 2, so 0.5 mol of Mg forms 0.5 mol of H 2. Mass of H 2 = M r × amount = 2 × 0.5 = 1 g.
