We write the stoichiometric equation....

#CaCO_3(s) + Delta rarr CO_2(g)uarr + CaO(s)#

Explanation:

And thus is 1:1 molar equivalence between calcium carbonate and carbon dioxide...

#"Moles of calcium carbonate"=(1.0*g)/(100.09*g*mol^-1)=0.010*mol#

And thus we get #0.010*mol# of carbon dioxide ON heating...And since we know that #1*mol# of ideal gas occupies a volume of #22.4*L#...we get a volume of....

#0.010*molxx22.4*L*mol^-1=??*L#
