The mass per cent of `H_2O_2` in '30 volume `H_2O_2` is

A

0.0456

B

0.0911

C

0.1139

D

0.1367

Text Solution

Verified by Experts

The correct Answer is:
B
Strength of 30 volume `H_(2)O_(2)` = (molarity ) ( molar mass ) = `{ (2 xx 30 //22.4 ) mol L^(-1)} (34 " g mol"^(-1)) = 91.1 g L^(-1)`
Mass per cent of `H_(2) O_(2) = 9.11 % `
