Silver fully dissolves in hot concentrated nitric acid which acts as an oxidizing agent to form the water-soluble silver nitrate and a brown gas. 
Ag (s) + 2 HNO₃ (aq) → AgNO₃ (aq) + NO₂ (g) + H₂O (l)
Determine whether 40.0 g of HNO₃ is enough to dissolve 30.0 g of Ag. 

• A. Yes, 40.0 g of HNO₃ is enough to dissolve 30.0 g of Ag and can dissolve up to around 34.2 g of Ag.
• B. Yes, 40.0 g of HNO₃ is enough to dissolve 30.0 g of Ag and can dissolve up to around 68.5 g of Ag.
• C. Yes, 40.0 g of HNO₃ is enough to dissolve 30.0 g of Ag and can dissolve up to around 80.0 g of Ag.
• D. No, 40.0 g of HNO₃ is not enough to dissolve 30.0 g of Ag since it can only dissolve up to around 20.0 g of Ag.
