AgNO3(aq) + HCl(aq) → AgCl(s) + HNO3(aq)

Molarity (M)=molL


50.0 mL of 0.100 M AgNO3 

mol AgNO3=50.0 mL×10-3 L1 mL×0.100 molL

mol AgNO3 = 0.005 mol


50.0 mL of 0.100 M HCl

mol HCl=50.0 mL×10-3 L1 mL×0.100 molL

mol HCl = 0.005 mol

The addition of hydrochloric acid to a silver nitrate solution precipitates silver chloride according to the reaction:

AgNO3(aq) + HCl(aq) → AgCl(s) + HNO3(aq)

When 50.0 mL of 0.100 M AgNO3 is combined with 50.0 mL of 0.100 M HCl in a coffee-cup calorimeter, the temperature changes from 23.40 oC to 24.21 oC. Calculate ΔHrxn for the reaction as written. Use 1.00 g/mL as the density of the solution and C = 4.18 J/g°C as the specific heat capacity.
