Ethanol, C2H5OH has the melting point of -117.3 degrees C and the boiling point of 78.3 degrees C. how much?

ethanol, C2H5OH has the melting point of -117.3 degrees C and the boiling point of 78.3 degrees C. how much heat (in kJ) is needed to convert 43.1 g of solid ethanol at -117.3 degrees C to liquid ethanol at 78.3 degrees C? (the specific heat of ethanol is 2.46 J/g * degrees C, deltaH(fus)= 7.61 kJ/mol, delta(vap)= 39.3 kJ/mol.)
