A dissolution process/reaction was performed in a coffee cup calorimeter. The initial temperature was 23.7°C and the final temperature was 25.7°C. The s of the solution is assumed to be 4.184 J/g°C and the mass of the solution was 47 grams. If there were 1.62 moles of the substance being dissolved, what i (the process/reaction aka the system) in J/mol? Round your answer to three sig figs and make sure you include the sign.

QUESTION 2
A dissolution process/reaction was performed in a coffee cup calorimeter. The initial temperature was 23.7°C and the final temperature was 25.7°C. The specific heat capacity
of the solution is assumed to be 4.184 J/g°C and the mass of the solution was 47 grams. If there were 1.62 moles of the substance being dissolved, what is AH of dissolution
(the process/reaction aka the system) in J/mol?
Round your answer to three sig figs and make sure you include the sign.
AH = 9sys /n
