How would you figure: How much energy, in kJ, is absorbed by 23.8 g of acetone when it evaporates if its molar heat of vaporization is 32.0 kJ/mol? Acetone formula is C3H6O

I think I did this for you (someone anyway) yesterday.

Convert grams acetone to mols. mol = grams/molar mass
q = mols acetone x delta Hvap/mol = ? kJ.
