For this question, assume that methane acts as an ideal gas. The gas laws are summarised by the ideal gas equation $pV = nRT$. A methane sample has its volume measured at $60\,^{\circ}\text{C}$ and a pressure of $103\,\text{kPa}$. The measured volume is $5.37 \times 10^{-3}\,\text{m}^3$. What is the mass of the methane sample, to two significant figures?
- A0.0032 g
- B0.018 g
- C3.2 g
- D18 g
