Problem: Silver bromide is used to coat ordinary black-and-white photographic film, while high-speed film uses silver iodide.(a) When 50.0 mL of 5.0 g/L AgNO3 is added to a coffee-cup calorimeter containing 50.0 mL of 5.0 g/L NaI, with both solutions at 25°C, what mass of AgI forms?(b) Use Appendix B to find ΔH°rxn.

(a) AgNO3 (aq) + NaI (aq) → AgI (s) + NaNO3 (aq)
= 0.392 g AgI
