If 25.0 kJ of heat is lost by 0.500 mol of substance A initially at 110 °C, what is the final temperature of substance A? For substance A: molar heat of vaporization = 43.4 kJ/mol molar heat of fusion = 4.9 kJ/mol molar heat capacity of the liquid = 112.4 J/mol·K molar heat capacity of the gas = 37.12 J/mol·K Select one: a. 78 °C b. 52 °C c. 83 °C
