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

Answer»

24.16
22.8
30.16
25.8

SOLUTION :Molarity=`"Weight of solute GM"/"Molecular massx 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
