Solid lithium perchlorate dissolves in water according to the equation below. LiClO4 (s) ➝ Li+ (aq) + ClO4 – (aq)       ΔHº = –26.55 kJ/mol 7.00 grams of solid LiClO4 dissolves in 40.0 grams of water initially at a temperature of 29.00 ºC in a perfect calorimeter. Calculate the final temperature of the solution in the calorimeter. [You may assume that no heat escapes the calorimeter and that all solutions have the same specific heat capacity as pure water (4.184 J/g·ºC)]
