Question
To what extent must a given solution of concentration of 40 mg silver nitrate per ml be diluted to yield a solution of concentration of 16 mg silver nitrate per ml?
Options
A.Each ml should be diluted to 2.5 ml
B.To each ml of solution, 1.5 ml of water should be added
C.To 2.5 ml of solution, 2 ml of water should be added
D.To 1.5 ml of solution, 1.5 ml of water should be added
Solution
$V_{1} \times 40 = V_{2} \times 16 \Rightarrow \frac{V_{2}}{V_{1}} = \frac{2.5}{1}$
