Heat of Vaporization

[Maria Davila 2I]

For question 7.35 in the textbook it asks to find the enthalpy of vaporization for . What is given is the 0.579 mol of and the heat required 4.76kJ. The solution manuals offers that

Would the equation used to solve this problem be ?

Just wanted to clarify .

Yes you could use that equation, but I think the equation that the solutions manual is easier to understand and you don't have to memorize. Enthalpies of vaporization and fusion are always given in kJ/mol, so if you use the first equation then the units make sense.

Thank you Justin, that makes it easier to understand (looking at the units). Thanks !
