Answer
See the answer below.
Work Step by Step
a) It should be lower because allyl alcohol has a O-H group and displays hydrogen bonding; therefore, it is less volatile.
b) Using a regression, it follows: $ln\ P=-3871.1/T+18.383$
$\Delta H_v=-3871.1\ K×-0.008314\ kJ/mol.K=32.18\ kJ/mol$
c) $d=m/V=PM/RT$
$M=(1.53\ g×0.082×295\ K)/((0.264\ L) (722/760×1\ atm))$
$M=147.67\ g/mol$
$147.67=3×12.011+(6-x)×1.008+18.998×x+15.9994$
$89.59=17.990×x$
$x=4.98$
