🤓 Based on our data, we think this question is relevant for Professor Marville's class at UIUC.
Consider the following reaction:
NaCl (s) → Na+ (aq) + Cl- (aq) ΔH = 3.88 kJ/mol
In a coffee-cup calorimeter you dissolve 21.9 g of this salt in 108 g of water at 27.7°C.
What will be the final temperature of the solution formed?
Assume the specific heat of the solution is 4.184 J/g°C, and that there is no heat loss to the surroundings. Please enter your answer to the correct number of significant figures.
