The \% \(\left(\frac{W}{V}\right)\) of \(\mathrm{H}_2 \mathrm{O}_2\) in \(1.5 \mathrm{~N}\) solution is
- A \(3.6\)
- B \(2.99\)
- C \(2.55\)
- D \(2.4\)
Answer & Solution
Correct Answer
(C) \(2.55\)
Step-by-step Solution
Detailed explanation
We know, Normality \(=2 \times M\) \(\begin{aligned} & M=\frac{1.5}{2}=0.75 \\ & M=\frac{\text { mass }}{\text { mol. mass } \times V(\mathrm{~L})}\end{aligned}\) mass \(=0.75 \times 34 \times \mathrm{L}\) \(=25.5\) \(\% \frac{W}{V}=25.5 \times \frac{100}{1000}\) \(=2.55\).
