When 5.93 g of potassium sulfate (K,SO4) is dissolved in 111 g of water in a styrofoam calorimeter of negligible heat capacity, the temperature drops from 25.00 to 23.21 °C. Based on this observation, calculate q for the water and AH° for the process, assuming that the heat absorbed by the salt is negligible. K2SO4(s) 2K*(aq) + SO42- (aq) The specific heat of water is 4.184 J °C1 g1. Give the answers in kJ. kJ 9H20 = AH° = kJ Not submitted
