6L `H_2O_2` contains 440 gm solute than how much litre `O_2` gas will produce from this solution at STP ?

A

24.16

B

22.8

C

30.16

D

25.8

Text Solution

Verified by Experts

The correct Answer is:
A
Molarity=`"Weight of solute gm"/"Molecular mass x Volume of solution in litre"`
`=440/(34xx6)=2.156 M H_2O_2`
`V(O)_2`= M x 11.2
= 2.156 x 11.2
=24.16 L `O_2` gas
