When heated strongly, solid calcium carbonate decomposes to produce solid calcium oxide and carbon dioxide gas, as represented by the equation above. A sample of CaCO3 is placed in a rigid 35L reaction vessel from which all the air has been evacuated. The vessel is heated to 437°C at which time the pressure of CO2 in the vessel is constant at 1.00atm. Calculate the number of grams of CO2 gas that are present after the reaction completes.
