Answer:
1 mole of CaCO3 produces = 1 mole of CO2. So 0.1 mole of CO2 produces= 0.1 mole of CO2. 0.1 mole of CO2 will occupy a volume of = 22.4 x 0.1= 2.24 Litres.

Answer:
2.24 L CO2 will be produced in the decomposition.
Explanation:
We know the reaction for decomposition of CO2 from CaCO3:
CaCO3(s) → CaO(s) + CO2(g) ... equation (1)
From equation (1);
We get 1 mole CaCO3(s) produces 1 mole CO2(g).
Molecular mass of CaCO3 = 100.0869 g/mol
So, 1 mole CaCO3 = 100 g CaCO3
Hence we get;
So 0.1 mole CO2 will be produced in the decomposition of 0.1 mole CaCO3.
In S.T.P the volume of 1 mole CO2 = 22.4 L
So, we get volume of 0.1 mole CO2 in STP is = 2.24 L
Hence 2.24 L CO2 will be produced.
