Question

Acetic anhydride, C4H6O3, has a normal boiling point of 139.8 C (ie, at 1.013 bar) and a standard enthalpy of vaporization of 51. 9 KJ mol^-1. What is the vapour pressure of acetic anhydride at room temperature (298 K) in units of bar?

Can someone help me solve this question, it'll be deeply appreciated.
