If you are using 3.00% (mass/mass) hydrogen peroxide solution and you determine that the mass of solution required to reach the equivalence point is 5.125 g, how many moles of hydrogen peroxide molecules are present?

0.004522 moles of hydrogen peroxide molecules are present.

Explanation:

Mass by mass percentage of hydrogen peroxide solution = w/w% = 3%

Mass of the solution , m= 5.125 g

Mass of the hydrogen peroxide = x

Mass of hydregn pervade in the solution = 0.15375 g

Moles of hydregn pervade in the solution :

0.004522 moles of hydrogen peroxide molecules are present.

where are the choice options?
