A 114.8 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 = 78.11 kJ/mol; normal boiling point, Tb = 160.3 C) How much energy (in kJ) is absorbed/released to condense the gas? also How much energy (in kJ) is absorbed/released to cool the gas?
