That's a correct mass of hydrogen peroxide, but that's not a recipe.

To be honest I don't see how to answer the question without knowing what you can use to prepare the solution. Commercially hydrogen peroxide is sold in may different form (solutions of different concentrations), not knowing which one will be used it is impossible to give an answer.
