Question

What is the maximum volume, in dm3, of CO2(g) produced when 1.00 g of CaCO3(s) reacts with 20.0 cm3 of 2.00 mol\(\,\)dm–3 HCl(aq)?

CaCO3(s) + 2HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)

Molar volume of gas = 22.7 dm3\(\,\)mol–1; Mr(CaCO3) = 100.00

A.     \(\frac{1}{2} \times \frac{{20.0 \times 2.0}}{{1000}} \times 22.7\)

B.     \(\frac{{20.0 \times 2.0}}{{1000}} \times 22.7\)

C.     \(\frac{{1.0}}{{100.00}} \times 22.7\)

D.     \(\frac{{1.0}}{{100.00}} \times 2 \times 22.7\)
