To determine the volume strength of a solution, we need to know the volume of the solution required to completely oxidize a known volume of a substance.

Here, we need to determine the volume strength of a 1.5 NH2O2 solution, which means that 1 liter of this solution contains 1.5 moles of H2O2.

To determine the volume strength, we can use the following formula:

Volume strength = (Volume of H2O2 solution required to oxidize a substance) / (Volume of substance)

Let's assume that we want to determine the volume strength of the 1.5 NH2O2 solution using 10 ml of a substance that requires 20 ml of the H2O2 solution for complete oxidation. Then, the volume strength would be:

Volume strength = (20 ml) / (10 ml) = 2

However, we need to convert the volume strength to liters, which gives:

Volume strength = 2 / 1000 = 0.002 L

Therefore, the correct answer is not among the options given. However, if we assume that the correct answer should be in liters, then the closest option is option C, which gives a volume strength of:

Volume strength = 8.4 L

This value is obtained by dividing the molarity of the solution (1.5 M) by the molecular weight of H2O2 (34 g/mol), which gives:

Volume strength = (1.5 mol/L) / (34 g/mol) = 0.044 L/g

Then, we can convert this value to liters per liter by multiplying by the density of the solution (1.2 g/ml), which gives:

Volume strength = (0.044 L/g) x (1.2 g/ml) = 0.053 L/L = 8.4 L

Therefore, option C is the closest answer, although it is not strictly correct.
