Calculate the mass and amount of carbon monoxide substance (lV) formed during the decomposition of 10 g of calcium carbonate CaCO3.

Given:
m (CaCO3) = 10g
m (CO2) -?
m (CO2) -?
Decision:
n (CaCO3) = 10 \ 100 = 0.1 mol
CaCO3 → CaO + CO2
n (СО2) = 0.1 mol
m (CO2) = 0.1 * 44 = 4.4g
Answer: n (CO2) = 0.1 mol; m (СО2) = 4.4g
