A liquid substance has a vapor pressure of 450.0 mmHg at 262.0 degrees celsius and 760.0 mmHg at 325.0 celsius. a) what is the heat of vaporization of this substance? b) what is its normal boiling point?

I know i have to use the clausius-clapeyron equation. But when multiplying the temperature in Kelvin and the gas constant I dont know why I never get the answer. can someone explain what exactly im multiplying on the computer. I usually mess up with parenthesis or something.
