Question

The main component of nail polish remover is acetone, which has ∆Hvap= +31.3 kJ/mol. How many kJ of energy will be exchanged between your skina dn 48.9 mL of acetone which have been spilled on you? (density of acetone =0.79 g/cm^3)

Mass of acetone = volume x density.
Calculate mass.

moles = grams/molar mass
Calculate moles acetone.

delta Hvap = 31.3 kJ/mol.
Calculate heat transfer.
thank you! i completely understand it now!
