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) 61.0 g. 35.7% yield 179 g. 12.2 % yield 91.7 g. 23.8 % yield 206 g. 10.6 % yield 27.1 g, 80.4 % yield
