Question

Commercial $11.2$ volume of $H_2{O}_2$ solution has a molarity of______

Answer 1

Step 1: Formula of molarity

$\mathrm{Molarity}=\frac{\mathrm{Volume}\mathrm{of}\mathrm{chemical}\left(\mathrm{L}\right)}{22.4}$

Step 2: Calculating the Molarity

${\mathrm{Volume}}_{\left({\mathrm{H}}_2{\mathrm{O}}_2\right)}=11.2\mathrm{L}$

$\mathrm{Molarity}=\frac{11.2}{22.4}\mathrm{M}$

$\mathrm{Molarity}=0.5\mathrm{M}$

Final Answer:

Therefore, the molarity of hydrogen peroxide is $0.5\mathrm{M}$.
