Homework Problem 8.37

Postby GabrielaGutierrez2A » Sat Jan 28, 2017 3:43 pm


Does anyone know how to do 8.37? It reads:

At its boiling point, the vaporization of 0.579 moles of methane requires 4.76 KJ of heat. What is the enthalpy of vaporization of methane?

You divide the amount of heat by the number of moles to get 8.22 kJ/mol. This is because the problem tells you that that's the amount of energy it takes to for that amount of moles of methane to vaporize, so all you have to do is put in the the standard kJ per mole notation.
