The volume strength of 1M H _ 2 O _ 2 is: (Molar mass of H _ 2 O _...

The volume strength of

1\text{M}{\text{H}}_{2}{\text{O}}_{2}

is:

(Molar mass of

{\text{H}}_{2}{\text{O}}_{2} = 34\text{g}\text{mol}{}^{- 1}

)

Options

A $5.6$
B $22.4$
C $11.2$
D $16.8$

Correct answer

C. $11.2$

Step-by-step solution

{\text{H}}_{2}{\text{O}}_{2} \to {\text{H}}_{2}\text{O} +

\dfrac{1}{2}{\text{O}}_{2}

\text{Volume strength} = 11.2 \times \text{Molarity}

= 11.2 \times 1

= 11.2
