Question

Geraniol, a volatile organic compound, is a component of rose oil. The density of the vapour is 0.46 gL–1 at 257°C and 100 mm Hg. The molar mass of geraniol is ____ g mol –1. (Nearest Integer) [Given: R = 0.082 L atm K–1 mol–1]

Answer 1

The correct answer is: 152

$\frac{PM}{RT}=d=M=\frac{0.46×0.082×530×760}{100}$

≃ 152 g mol–1
