Atoms, molecules and stoichiometry — practice question

For this question, take the gas produced to behave as an ideal gas. A $1.7\ \text{g}$ sample of $\text{Mg}$ reacts with $50.0\ \text{cm}^3$ of $2.2\ \text{mol dm}^{-3}\ \text{HCl}$ at $303\ \text{K}$ and $110\,400\ \text{Pa}$. What volume of gas is formed when measured under these conditions?

  • A$1.3\ \text{dm}^3$
  • B$1.6\ \text{dm}^3$
  • C$2.5\ \text{dm}^3$
  • D$5.0\ \text{dm}^3$
