Question

How much mass of silver nitrate will react with $5.85\, g$ of sodium chloride to produce $14.35 \,g$ of silver chloride and $8.5\, g$ of sodium nitrate if law of conservation of mass is followed?

• A. $22.85\,g$
• B. $108\,g$
• C. $17.0\,g$
• D. $28.70 \,g$

Answer 1

Answer: (C)

$17.0\,g$

Answer 2

$\underset{\text{x}}{ {Ag NO_3}}$+ $\underset{\text{5.85g}}{ {NaCl}}$ ${->}$ $\underset{\text{8.5 g}}{ {NaNO_3}}$ + $\underset{\text{14.35 g}}{ {AgCl}}$ $x + 5.85 = 8.5 + 14 .35$ $\Rightarrow x = 17\, g$
