Strength of 10 volume Hydrogen peroxide solution means

A

30.35gL−130.35gL^{- 1}

B

17gL−117gL^{- 1}

C

34gL−134gL^{- 1}

D

68gL−168gL^{- 1}

Answer

30.35gL−130.35gL^{- 1}

Explanation

Solution

: 2H2O268g→2H2O+O222.4LatSTP\underset{68g}{2H_{2}O_{2}} \rightarrow 2H_{2}O + \underset{22.4LatSTP}{O_{2}}

22.4LO222.4LO_{2}is given by 68 g of H2OH_{2}O

10 L O2O_{2}is given by 6822.4×10=30.35gL−1\frac{68}{22.4} \times 10 = 30.35gL^{- 1}
