A 417.3 grаm sаmple оf аn unknоwn substance (MM = 92.41 g/mоl) is heated from -23.1°C to 51.8°C. The substance is heated under normal atmospheric conditions. Its heat capacity as a solid is 2.96 J/g･°C Its heat capacity as a liquid is 1.75 J/g･°C Its ∆Hfus = 8.04 kJ/mol with a normal freezing point of 17.6°C. For full credit, be sure to answer all three of the following questions: How much energy (in kJ) is absorbed/released to heat the solid? How much energy (in kJ) is absorbed/released to melt the solid? How much energy (in kJ) is absorbed/released to heat the liquid?
