Calculation of the Strength of H2O2 Solution

To calculate the strength of the H2O2 solution, we need to determine the percentage of H2O2 present in the solution. In this case, we have a sample of 10 volumes of the solution.

Step 1: Determine the volume of H2O2 in the solution
To determine the volume of H2O2 in the solution, we need to multiply the sample volume by the percentage strength.

For option A) 3% strength:
Volume of H2O2 = 10 volumes × (3/100) = 0.3 volumes

For option B) 4.04% strength:
Volume of H2O2 = 10 volumes × (4.04/100) = 0.404 volumes

For option C) 2.509% strength:
Volume of H2O2 = 10 volumes × (2.509/100) = 0.2509 volumes

For option D) 3.035% strength:
Volume of H2O2 = 10 volumes × (3.035/100) = 0.3035 volumes

Step 2: Calculate the strength percentage
To calculate the strength percentage, we need to divide the volume of H2O2 by the total volume of the solution and multiply by 100.

For option A) 3% strength:
Strength percentage = (0.3 volumes / 10 volumes) × 100 = 3%

For option B) 4.04% strength:
Strength percentage = (0.404 volumes / 10 volumes) × 100 = 4.04%

For option C) 2.509% strength:
Strength percentage = (0.2509 volumes / 10 volumes) × 100 = 2.509%

For option D) 3.035% strength:
Strength percentage = (0.3035 volumes / 10 volumes) × 100 = 3.035%

Conclusion:
Based on the calculations, the strength of the H2O2 solution is as follows:
A) 3% strength
B) 4.04% strength
C) 2.509% strength
D) 3.035% strength
