I need help in solving this problem:

A certain substance has a heat of vaporization of 42.46 kJ/mol. At what Kelvin temperature will the vapor pressure be 5.00 times higher than it was at 291 K?

I know that I have to use the Clausius-Clapeyron equation, but what would I be solving for essentially?

Thanks for the help!!!

You know p1 = P

and p2 = 5P1

You know T1 = 291

You solve for T2.
