Question

the concentration of a solution of h2o2 is 6.8% then the volume concentration of the solution is​

Answer 1

Dear Savita,

● Answer -

v/v = 4.48 %

● Explaination -

# Given -

w/w = 6.8 %

v/v = ?

# Solution -

Concentration by weight of H2O2 is given.

w/w = 6.8 %

Concentration by volume of H2O2 soln is calculated by -

v/v = 22.4 / M × w/w

v/v = 22.4 / 34 × 6.8

v/v = 4.48 %

Therefore, concentration by volume of given H2O2 soln is 4.48 % .

Hope you understand..

Answer 2

Answer: 22.4

Explanation:

Volume concn=112*6.8/34

=22.4
