< Mentor Note -- thread moved to HH from the technical forums, so no HH Template is shown > The experiment I'm trying to do can be found in the attachment below. Prepare 20 mL solutions of hydrogen peroxide in the following concentrations: 0%,0.5%, 1.0%, 1.5%, 2.0%, 2.5%, 3.0% hydrogen peroxide. I'm starting with hydrogen peroxide at 3% concentration. How do I to get these concentrations? What measurement tools do you need to do this? I'm not a chemist so I have no idea. Is it dilution?
