(B) Using the ideal gas equation $PV = nRT$,where $n = \frac{m}{M}$ and $d = \frac{m}{V}$,we get $P = \frac{dRT}{M}$.Rearranging for molar mass: $M = \frac{dRT}{P}$.Given values:$d = 0.46 \, g \, L^{-1}$$R = 0.082 \, L \, atm \, K^{-1} \, mol^{-1}$$T = 257 + 273 = 530 \, K$$P = \frac{100}{760} \, atm$Substituting these values:$M = \frac{0.46 	imes 0.082 	imes 530 	imes 760}{100}$$M = 151.93 \, g \, mol^{-1}$.Rounding to the nearest integer,we get $152$.

Geraniol,a volatile organic compound,is a component of rose oil. The density of the vapour is $0.46 \, g \, L^{-1}$ at $257^{\circ} C$ and $100 \, mm \, Hg$. The molar mass of geraniol is $....$ (Nearest Integer) [Given $R = 0.082 \, L \, atm \, K^{-1} \, mol^{-1}$]
