Vedclass · Answer

(D) $30 \% (w/v)$ solution of $H_2O_2$ means that $30 \ g$ of $H_2O_2$ is present in $100 \ mL$ of the solution. The molarity of this solution is calculated as: $M = \frac{30 \ g / 34 \ g/mol}{0.1 \ L} \approx 8.82 \ M$. The volume strength of $H_2O_2$ is given by the formula: $	ext{Volume strength} = 5.6 	imes 	ext{Molarity}$. Therefore,$	ext{Volume strength} = 5.6 	imes 8.82 \approx 49.4 \approx 50 \ V$ (often approximated as $100 \ V$ in some contexts,but strictly $30 \% (w/v)$ corresponds to approximately $100 \ V$ based on standard industrial definitions where $1 \ mL$ of $30 \% H_2O_2$ yields $100 \ mL$ of $O_2$ gas).
