Question
i need the answer quickly
In a coffee-cup calorimeter, 29.8 g sample of solid KCI is dissolved in 100.0 g of water at 15.0 °C. The temperature in the calorimeter is measured to be 2.9 °C when the dissolution of KCl is completed. Assuming that the specific heat of solution is equal to that of water, i.e., 4.184 J/g °C, calculate the heat of solution of KCI in water, in k]/mol. ((MM)KCI = 74.55 g/mol) %3D
