what are you on about? it says find the final temperature, given that the intial temperature is 18 so you plus 1.986 with 18

You're working for finding the change in temperature was confusing. I just clarified it for everyone else.

i dnt get why you multiplied the 83kj by the 0.01. can you please explain.

Because 83kJ of heat is released when 1 mol of Calcium Chloride is dissolved. The question states 0.01 mol is used so 0.01mol x 83kJ/mol = amount of heat released by 0.01 mol
