Question

H2O solution used for hair bleaching is sold as solution of approx 5.0gm H2O2 per 100 ml of the solution. The volume strength of the H2O2
​

Answer 1

Answer:

Explanation:

no.of moles of H202 =5/34=0.15 moles

 molarity =0.15/100(ingram)    *1000=0.0015*1000 =1.5 M

molarity of H202=volume stenght of H202/11.2

1.5M*11.2   =volume strength of h202

volume strenght of H202=16.8

if wrong let me know

Answer 2

Answer:

The molarity of this solution is approximately 1.5 mol/L.

Explanation:

Man of H 2 O 2 = 5 g

molar man of H 2O2 = 34

number of mole = 5/34 = 0.147

morality 0.147/ 100 m.p×10 −3  = 1.47M≃1.5M
