Using the below information, calculate the amount of heat needed to take 100g

Question
Using the below information, calculate the amount of heat needed to take 100g of Substance X from a liquid state at its melting point to the gaseous state at its boiling point. The molar mass of substance X is 78.11 g/mol)

Physical Constants for Substance X

ΔHvap = 33.9 kJ/mol

ΔHfus = 9.81 kJ/mol

csolid = 1.51 J/gºC

cliquid = 1.73 J/gºC

cgas = 1.06 J/gºC

Tmelt = 279.0K

Tboiling = 353.0 K
