The represented substance has the following heat capacities, enthalpy of fusion, and enthalpy of vaporization.

cp, solid = 3.2 j/(g•°c); cp, liquid = 5.3 j/(g•°c);
cp, vapor = 8.9 j/(g•°c); δhfus = 4.5 kj/mol;
δhvap = 8.6 kj/mol

calculate the total energy input required to accomplish vaporization of one mole of substance at 15°c. the molar mass of the substance is 120.0 g/mol.
