(D) According to the Ideal Gas Law,$PV = nRT = (\frac{W}{M})RT$.Since $P, V, T$ are constant,$n_1 = n_2$,which implies $\frac{W_1}{M_1} = \frac{W_2}{M_2}$.Given $W_1 = 0.6 \ g$ (for $N_2$,$M_1 = 28 \ g \ mol^{-1}$) and $W_2 = 0.73 \ g$.Substituting the values: $\frac{0.6}{28} = \frac{0.73}{M_2}$.$M_2 = \frac{0.73 \times 28}{0.6} = \frac{20.44}{0.6} \approx 34.06 \ g \ mol^{-1}$.The molar mass of $PH_3$ is $31 + 3(1) = 34 \ g \ mol^{-1}$.Therefore,the gas is $PH_3$.
