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
