Question:
Calculate the speed of sound in oxygen from the following data. The mass of $22.4$ litre of oxygen at STP ( $T=273 \mathrm{~K}$ and $p=$ $1.0 \times 10^{5} \mathrm{~N} \mathrm{~m}^{-2}$ ) is $32 \mathrm{~g}$, the molar heat capacity of oxygen at constant volume is $C_{\mathrm{V}}=2.5 \mathrm{R}$ and that at constant pressure is $C_{p}=3.5 \mathrm{R}$.
