(B) The density $d$ of an ideal gas is given by the formula $d = \frac{PM}{RT}$.At $STP$,$P_1 = 1 \, atm = 760 \, torr$,$T_1 = 273.15 \, K$,and $d_1 = 1.43 \, g \, L^{-1}$.At the new condition,$P_2 = 800 \, torr$,$T_2 = 17 + 273.15 = 290.15 \, K$.Since $M$ and $R$ are constant,we have $\frac{d_1 T_1}{P_1} = \frac{d_2 T_2}{P_2}$.Rearranging for $d_2$: $d_2 = d_1 	imes \frac{P_2}{P_1} 	imes \frac{T_1}{T_2}$.Substituting the values: $d_2 = 1.43 	imes \frac{800}{760} 	imes \frac{273.15}{290.15}$.$d_2 = 1.43 	imes 1.0526 	imes 0.9414 \approx 1.417 \, g \, L^{-1}$.

If the density of dioxygen gas at $STP$ is $1.43 \, g \, L^{-1}$,calculate its density at $17 \, ^\circ C$ and $800 \, torr$ pressure.
