What volume of `CO_(2)` is obtained at STP by heating 4 g of `CaCO_(3)` ?

Explanation

Chemical Equation is
`CaCO_(3)overset(Delta)to CaO+CO_(2)`
1 mole `CaCO_(3)to 1 " mole" CO_(2)` at STP
100 gms of `CaCO_(3)to 22.4 " lit of" CO_(2)` at STP
4 gms of `CaCO_(3)to ? `
`(4 xx 22.4)/(100)=0.896` " lit"
