Can you show me how to set up this problem? I don't reallyunderstand how to incorporated heat of fusion as well as heat ofvaporization into this problem..

Calculate the heat required to convert 14.7 g of ethyl alcohol,C2H6O, from a solid at -144°C into the gaseous state at 95°C. The normal melting and boiling points ofthis substance are -117°C and 78°C, respectively. Theheat of fusion is 109 J/g, and the heat ofvaporization is 837 J/g. The specific heats of the solid,liquid and gaseous states are, respectively, 0.97, 2.30 and 0.95J/g/K.
