The Data Booklet is needed for this question. When $0.15\,\text{g}$ of an organic compound is vaporised, it takes up a volume of $65.0\,\text{cm}^3$ at $405\,\text{K}$ and $1.00 \times 10^5\,\text{N m}^{-2}$. Using the equation $pV = nRT$, which of the following expressions should be used to work out the relative molecular mass, $M_r$, of the compound?
- A$\dfrac{0.15 \times 65 \times 10^{-6} \times 1 \times 10^{5}}{8.31 \times 405}$
- B$\dfrac{0.15 \times 8.31 \times 405}{1 \times 10^{5} \times 65 \times 10^{-3}}$
- C$\dfrac{0.15 \times 65 \times 10^{-3} \times 1 \times 10^{5}}{8.31 \times 405}$
- D$\dfrac{0.15 \times 8.31 \times 405}{1 \times 10^{5} \times 65 \times 10^{-6}}$
