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) $d=m/V=PM/RT$ $M=(1.53\ g×0.082×295\ K)/((0.264\ L) (722/760×1\ atm))$ $M=147.67\ g/mol$ $147.67=3×12.011+(6-x)×1.008+18.998×x+15.9994$ $89.59=17.990×x$ $x=4.98$
