$A$ reagent that can distinguish between a chloride and a peroxide is

The strength of $50$ volume solution of hydrogen peroxide is $...... \ g/L$ (Nearest integer). Given: Molar mass of $H_2O_2$ is $34 \ g \ mol^{-1}$. Molar volume of gas at $STP = 22.7 \ L$.

How many millilitres of $3 \% \left( \frac{w}{v} \right) H_2O_2$ solution is required to get $150 \ mL$ of oxygen at $STP$?

The normality of $30$ volume $H_2O_2$ is (in $N$)

The species that is not hydrolysed in water is

The strength of $H_2O_2$ sample available from market is $8.32\% \ W/V$. The volume and molar concentration of this sample are ......... and ........ respectively.
