Cаlcium cаrbоnаte, CaCO3(s), the principal cоmpоund in limestone, decomposes upon heating to CaO(s) and CO2(g). A sample of CaCO3 is decomposed, and the carbon dioxide is collected in a 2.50 L flask. After decomposition is complete, the gas has a pressure of 1.3 atm at a temperature of 31 °C. How many moles of CO2 gas were generated? Given the ideal gas law PV = nRT and the Ideal gas constant, R = 0.08206 L-atm/mol-K.
