50.0 grams of arsenic powder is mixed with 50.0 grams of oxygen gas. Given the following balanced equation, how many grams of arsenic trioxide is produced? (Molecular masses: Arsenic = 74.92 g/mol; Oxygen = 16.00; Diarsenic trioxide = 197.84 g/mol) Balanced Equation: 4As(s) + 3O2(g) –> 2As2O3(s) [HINT: How many equations are required to determine the answer?]
