Metallic silver reacts with nitric acid according to the following balanced equation.

$$3Ag(s)+4HN{ O }_{ 3 }(aq)\rightarrow 3AgN{ O }_{ 3 }(aq)+NO(g)+2{ H }_{ 2 }O(l)$$

The given molar mass for silver is 108 g/mol and for nitric acid is 63 g/mol.

Which of the following determines the minimum volume in milliliters (mL) of 8.0 M $HN{O}_{3}$ needed to dissolve 2.0 g of silver metal?

Units are not shown, and the values are in no particular order.

A

$\cfrac { 2.0\times 4 }{ 108\times 3\times 8.0 } $

B

$\cfrac { 2.0\times 4\times 1000 }{ 108\times 3\times 8.0 } $

C

$\cfrac { 4\times 2.0\times 8.0 }{ 108\times 3 } $

D

$\cfrac { 2.0\times 4\times 8.0 }{ 108\times 3\times 1000 } $
