In a coffee cup calorimeter 70.0 mL of 0.100 M AgNO3 and 70.0 mL of 0.100 M HCl are mixed to yield the following reaction.
Ag+(aq) + Cl ‾(aq) → AgCl(s)
If the two solutions are initially at 22.60°C, and if the final temperature is 23.39°C, calculate ΔH for the reaction in kJ/mol of AgCl formed. Assume a mass of 140.0 g for the combined solution and a specific heat capacity of 4.18 J °C-1 g-1.

And a density of 1.00 g/mL.
140 mL = 140 g liquid.

q = mass water x specific heat water x (Tfinal-Tinitial) = 0
You have mass and specific heat as well as Tf and Ti. solve for q. That is the heat generated. It is delta H, dH.
dH/0.007 mol gives dH/mol AgCl.
