How much nitric acid is required to dissolve one kilogram of silver?
Depends. Silver can be converted to silver nitrate with dilute, cold nitric acid or with concentrated nitric acid at elevated temperature. The stoichiometry of reactions is different and depend on the conditions used. The relevant reactions are
3 Ag + 4 HNO3 (cold and diluted) → 3 AgNO3 + 2 H2O + NO
Ag + 2 HNO3 (hot and concentrated) → AgNO3 + H2O + NO2
Now, Guy Clentsmith already worked things out for you for the second reaction and found that you would need at least 1.24 L of concentrated nitric acid. In the concentrated case the ratio of Ag:HNO3 was 1:2. In the dilute HNO3 case the ratio is 1:1.333. So, you will need less HNO3, about 1/3 less or 0.827 L of concentrated HNO3 (which would then have to dilute).
