The strength of 5050 volume solution of hydrogen peroxide is _____ g/Lg / L (Nearest integer).

Given:
Molar mass of H2O2{H}_{2}{O}_{2} is 34gmol−134g{mol}^{- 1}
Molar volume of gas at STP=22.7LSTP = 22 . 7L.

Correct answer

0

Step-by-step solution

Molarity =VolumestrengthofH2O2MolarvolumeofoxygengasatSTP×2= \dfrac{Volumestrengthof{H}_{2}{O}_{2}}{MolarvolumeofoxygengasatSTP} \times 2

Molarity =5011.35= \dfrac{50}{11 . 35}

The strength of the solution=Molarity×MolecularweightofH2O2= Molarity \times Molecularweightof{H}_{2}{O}_{2}

∴∴ Strength in gm/L=5011.35×34gm / L = \dfrac{50}{11 . 35} \times 34.
