In a coffee cup calorimeter, 50.0 mL of 0.100 M

Question

AgNO3 and 50.0 mL of 0.100 M HCl are mixed to yield
the following reaction:
Ag+ (aq) + Cl- (aq) -----------------> AgCl (s)
The two solutions were initially at 22.60 °C, and the final
temperature is 23.40 °C. Calculate the heat that
accompanies this reaction in kJ/mol of AgCl formed.
Assume that the combined solution has a mass of 100.0 g
and a specific heat of 4.18 J/g°C.

Answer 1

q rxn in J = mass soln x specific heat soln x delta T.
q rxn in kJ/mol = q rxn/0.005 = ?
(.005 comes from M x L = 0.1M x 0.05 L)
