Webb23 mars 2024 · Assume density 1 g/ml for 3% solution which gives 0.03 g $\ce{H2O2}$ per ml, or 30 g $\ce{H2O2}$ per liter. The molecular weight of $\ce{H2O2}$ is about 34 g/mol so: $\dfrac{30}{34} \approx 1$ molar. You want 100 mMolar which is 0.100 molar. Thus you need a 10 fold dilution. So add 10 ml of the 3% to 90 ml water to get 100 ml of …
