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?Hvap = 33.9 kJ/mol?Hfus = 9.81 kJ/molcsolid = 1.51 J/gºCcliquid = 1.73 J/gºCcgas = 1.06 J/gºCTmelt = 279.0KTboiling = 353.0 K
