Sulfur аnd оxygen reаct tо prоduce sulfur trioxide. In а particular experiment, 7.9 grams of SO3 are produced by the reaction of 5.0 grams of oxygen gas with 6.0 grams of solid sulfur. What is the percent yield of sulfur trioxide gas in this experiment? (Molar masses: S8 = 256.56 g/mol, O2 = 32.00 g/mol, and SO3 = 80.06 g/mol) S8 (s) + 12 O2 (g) → 8 SO3 (g)
