20.0 g of calcium carbonate is heated to produce carbon dioxide according to the equation CaCO3(s) → CaO(s) + CO2(g)?

20.0 g of calcium carbonate is heated to produce carbon dioxide according to
the equation
CaCO3(s) → CaO(s) + CO2(g)
If the reaction is carried out at a temperature of 800.0 degrees C and a constant pressure of
1.0 atm is maintained, what volume of carbon dioxide gas is recovered?
