The strength of 20 volume of `H_(2)O_(2)` is

A

13.6 g/L

B

60.7 g/L

C

160 g/L

D

20.2 g/L

Text Solution

Verified by Experts

The correct Answer is:
B
`underset(2xx34=68)(2H_(2)O_(2))to2H_(2)O+underset("22.4L at NTP")(O_(2))`
22.4 L of `O_(2)` at NTP is produced from 68 g of `H_(2)O_(2)`
20 L of `O_(2)` at NTP is produced from `(68xx20)/(22.4)=60.7` g of `H_(2)O_(2)`.
`therefore` Strength of `H_(2)O_(2)` in 20 vol. `H_(2)O_(2)=60.7` g/L
