The volume of oxygen liberated from `15 ml` of 20 volume `H_(2)O_(2)` is

A

`250 ml`

B

`300 ml`

C

`150 ml`

D

`200 ml`

Text Solution

Verified by Experts

The correct Answer is:
B
Quantity of `H_(2)O_(2)=15 ml` and volume of `H_(2)O_(2)=20`. We know that 20 volume of `H_(2)O_(2)` means 1 litre of this solutin will give 20 litres of oxygen at `N.T.P.`
Since, oxygen liverated from `1000 ml(1` litres `)` of `H_(2)O_(2)=20` litres, therefore oxygen liberate from `15 ml` of `H_(2)O_(2)=(20)/(1000)xx15=0.3`litre `=300ml`.
