What is the $\%$ strength of $22.4$ volume of $H_2O_2$ solution (in $\%$)?

In $H_2O_2$ molecule,the dihedral angle between the two $O-H$ planes is ............. $^o$.

Given below are two statements:
Statement $I$: $H_{2}O_{2}$ can act as both an oxidising and a reducing agent in a basic medium.
Statement $II$: In the hydrogen economy,the energy is transmitted in the form of dihydrogen.
In the light of the above statements,choose the correct answer from the options given below:

Calculate the molarity and $\% \ W/V$ of $40$ volume of $H_2O_2$ solution.
