Hey guys! I m still not sure about paper 5 chemistry, for example a question from Nov10/53 question 1
Using the apparatus shown in (c) design a laboratory experiment to test your prediction
in (a). In addition to the standard apparatus present in a laboratory you are provided with the
following materials.
• 2.00 mol dm–3 aqueous hydrogen peroxide
• a supply of manganese(IV) oxide
(i) Complete the table below to show how you would prepare five solutions of aqueous
hydrogen peroxide. Make sure that the correct units are recorded.
expt No. volume of H2 O2 volume of H2O concentration of H2O2

Note That: I dont understand where to get all the amounts to fill in to the table!
