question 84

Multiple Choice

Determine the theoretical yield and the percent yield if 21.8 g of K₂CO₃ is produced from reacting 27.9 g KO₂ with 29.0 L of CO₂ (at STP) .The molar mass of KO₂ = 71.10 g/mol and K₂CO₃ = 138.21 g/mol. 4 KO₂(s) + 2 CO₂(g) → 2 K₂CO₃(s) + 3 O₂(g)

• A) 27.1 g, 80.4% yield
• B) 179 g, 12.2% yield
• C) 91.7 g, 23.8% yield
• D) 206 g, 10.6% yield
• E) 61.0 g, 35.7% yield
