In a coffee cup calorimeter

In a coffee cup calorimeter, 50.0 ml of 0.100 M AgNO3 and 50.0 ml of 0.100 M HCl are mixed. The following reaction occurs:


If the two solutions are initially at 22.60∘C and if the final temperature is 23.40∘C, calculate ΔH for the reaction in kJ/mol of AgCl formed.
Assume a mass of 100.0 g for the combined solution and a specific heat capacity of 4.18 JC−1g−1
