Can you help me with this problem on diethyl ether?

Question

Diethyl ether was one of the first chemicals used as an anesthetic. At 34.6°C, diethyl ether has a vapor pressure of 760 torr, and at 17.9°C, it has a vapor pressure of 400 torr. What is the heat of vaporization for diethyl ether?

Answer 1

Refer to the Clausius-Claperyon equation which relates change in pressure and temperature to ∆H of vaporization.  If you still have a problem solving the problem after attempting it using these variable, re-submit the question with your workings.
