1.36 mоles оf аn unknоwn ionic compound is dissolved in 50.0 mL of wаter in а coffee cup calorimeter. The water is initially at 5.13°C, and the final temperature of the water after the ionic compound has fully dissolved is 8.21°C. Calculate DHsoln in kJ/mol of ionic compound. The density of water is 0.997 g/mL. Assume that the final solution is dilute enough to have the same density and specific heat capacity as pure water.
