Question

The volume of water to be added to $100c{m}^3$ of $0.5N{H}_{2}S{O}_4$ to get decinormal concentration is

• A. $100c{m}^3$
• B. $450c{m}^3$
• C. $500c{m}^3$
• D. $400c{m}^3$

Answer 1

The correct option is D

$400c{m}^3$

Let the total volume of solution = x

$\therefore V_2=\frac{N_1{V}_1}{N_2}=\frac{0.5\times 100}{0.1}=500c{m}^3$

$\therefore$ The volume of water added = 500 – 100

$400c{m}^3$
