Answer is: 4,4 grams of carbon dioxide gas would be produced.

Chemical reaction: CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O.

m (CaCO₃) = 10 g.

n (CaCO₃) = 10 g : 100 g/mol.

n (CaCO₃) = 0,1 mol.

From chemical reaction: n (CaCO₃) : n (CO₂) = 1 : 1.

n (CO₂) = 0,1 mol.

m (CO₂) = n (CO₂) · M (CO₂).

m (CO₂) = 0,1 mol· 44 g/mol.

m (CO₂) = 4,4 g.
