A 110.1 gram sample of an unknown substance (MM = 189.50 g/mol)is cooled from 233.0 °C to 147.6 °C. (heat capacity of liquid =1.62 J/g･°C; heat capacity of gas = 1.04 J/g･°C; ∆Hvap = 78.11kJ/mol; Tb = 160.3 °C)
A. How much energy (in kJ) is absorbed/released to cool thegas?
B. How much energy (in kJ) is absorbed/released to condense thegas?
C. How much energy (in kJ) is absorbed/released to cool theliquid?
D. What is the total amount of energy that must beabsorbed/released for the entire process?
