The mole and the Avogadro constant — practice question

Calcium carbonate undergoes reaction with dilute hydrochloric acid. The equation for this reaction is given below. $\text{CaCO}_3 + 2\text{HCl} \rightarrow \text{CaCl}_2 + \text{H}_2\text{O} + \text{CO}_2$ $1.00\,\text{g}$ of calcium carbonate is added to $50.0\,\text{cm}^3$ of $0.0500\,\text{mol dm}^{-3}$ hydrochloric acid. What volume of carbon dioxide is produced in this reaction?

  • A$30\,\text{cm}^3$
  • B$60\,\text{cm}^3$
  • C$120\,\text{cm}^3$
  • D$240\,\text{cm}^3$
