Solution: Determine the theoretical yield of K 2CO3 when 0.392 moles of KO 2 react with 29.0 L CO2 (at STP – 0°C, 1 atm). The molar mass of KO 2 = 71.10 g/mol and K 2CO3 = 138.21 g/mol. 4KO2(s) + 2CO2(g) → 2K2

Problem

Determine the theoretical yield of K 2CO3 when 0.392 moles of KO 2 react with 29.0 L CO2 (at STP – 0°C, 1 atm). The molar mass of KO 2 = 71.10 g/mol and K 2CO3 = 138.21 g/mol.

4KO2(s) + 2CO2(g) → 2K2CO3(s) + 3O2(g)
