How much volume of \(1 \mathrm{~N}\) aqueous solution of \(\mathrm{H}_2 \mathrm{SO}_4\) should be taken, which will contain 0.2 moles of \(\mathrm{H}_2 \mathrm{SO}_4\) ?
- A \(200 \mathrm{~mL}\)
- B \(400 \mathrm{~mL}\)
- C \(20 \mathrm{~mL}\)
- D \(40 \mathrm{~mL}\)
Answer & Solution
Correct Answer
(B) \(400 \mathrm{~mL}\)
Step-by-step Solution
Detailed explanation
\(\because\) Basicity of \(\mathrm{H}_2 \mathrm{SO}_4=2\) \(\therefore \quad 1 M=2 \mathrm{~m}\) Also, \(\quad N=\frac{n}{V}\) \(\therefore \quad N V=n\) \(1 \times V=0.2 \times 2=0.4\) \(\therefore \quad V=0.4 \times 1000\) Volume, \(\quad V=400 \mathrm{~mL}\)
