The molar heat of solution of a substance is found to be +35.34 kJ/mol. The addition of 0.20 moles of this substance to 1.5 L water initially at 55 degrees Celsius results in a temperature DECREASE. Assume the specific heat of the resulting solution to be equal to that of pure water. Find the final temperature of the solution.
