States of matter — practice question

The ideal gas equation $pV = nRT$ provides a summary of the gas laws. A methane sample has its volume measured at $60^{\circ}\text{C}$ and $103\text{ kPa}$. The recorded volume is $5.37 \times 10^{-3}\text{ m}^3$. If the gas is assumed to act as an ideal gas, what mass does the methane sample have, correct to two significant figures?

  • A$0.00018\text{ g}$
  • B$0.0032\text{ g}$
  • C$0.18\text{ g}$
  • D$3.2\text{ g}$
