    1. The problem statement, all variables and given/known data
    Describe how one would make a 100 mL solution of 0.1 M H2O2?

    2. Relevant equations

    3. The attempt at a solution
    to get no. of moles = ml*M/1000
    100*0.1/1000= 0.01 moles h202.

    mass= 0.01*34= 0.34 g.

    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.

    Thank you, My teacher gave us the recipe. i just wanted to check the mass number.
