11.77 g of a compound whose molar mass is 177.5 g/mol and whosemolar heat of solution is -68.0 kJ/mol are dissolved in water in aconstant-pressure calorimeter (coffee-cup calorimeter) thatcontains 94.28 g of water. The temperature of the mixture isinitially 21.34C. Calculate its final temperature in C. Assumethat the specific heat of the solution is the same as the specificheat of water.
