Answer:
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.
X is the chemical symbol of the element
The statement seems to be true, as per my knowledge.
Hope I helped!! xx
