Solution: When 0.100 mol of CaCO3(s) and 0.100 mol of CaO(s) are placed in an evacuated sealed 10.0-L container and heated to 385 K, PCO2 = 0.220 atm after equilibrium is established:   CaCO3(s) ⇌ CaO(s) + CO2(

Problem

When 0.100 mol of CaCO3(s) and 0.100 mol of CaO(s) are placed in an evacuated sealed 10.0-L container and heated to 385 K, PCO2 = 0.220 atm after equilibrium is established:   

CaCO3(s) ⇌ CaO(s) + CO2(g) 

An additional 0.300 atm of CO2(g) is pumped in. What is the total mass (in g) of CaCO 3 after equilibrium is re-established?
