Chemistry

Ethanol melts at -114.0 ∘C. The enthalpy of fusion is 5.02kJ/mol and the enthalpy of vaporization is 38.6 kJ/mol. Thespecific heats of solid and liquid ethanol are 0.970 J/g⋅K and 2.30J/g⋅K, respectively.

How much heat is needed to convert 39.0 g of solid ethanol at-160.0 ∘C to liquid ethanol at -35.0 ∘C ?

I am really confused on this, any help would be greatlyappreciated. Thanks!
