To find the volume concentration of a solution of H2O2, we first need to understand the given information.



The given concentration of the solution is 6.8% (w/V). This means that 6.8 grams of H2O2 is present in 100 milliliters of the solution.



To calculate the volume concentration, we need to find the volume of H2O2 present in the solution.

1. Convert the given concentration from percentage to grams per milliliter:
- 6.8% (w/V) means that there are 6.8 grams of H2O2 in 100 milliliters of the solution.
- Therefore, the concentration can be written as 6.8 grams/100 milliliters.

2. Use the concentration to find the volume of H2O2:
- The concentration is given in grams/100 milliliters, so the volume of H2O2 can be calculated using the formula:
Volume (in milliliters) = (Mass (in grams) / Concentration (in grams per milliliter)) * 100
- Substitute the given values into the formula:
Volume (in milliliters) = (6.8 grams / 6.8 grams per 100 milliliters) * 100
Volume (in milliliters) = 100 milliliters



The volume concentration of the solution of H2O2 is 100 milliliters. This means that for every 100 milliliters of the solution, there are 6.8 grams of H2O2 present.

Molecular mass of h2o2=(2*1+2*16)=34volume of the solution=molecular mass/concentration of the solutionvolume of the solution=34*100/6.8=500
