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 is 71.10 g mol-1 and K2CO3 is 138.21 g mol-1. 4KO2(s) + 2CO2(g) → 2K2CO3(s) + 3O2(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
