Not Telling
1) You could go to a grocery store or pharmacy and pick up a bottle of hydrogen peroxide -- the "home use" version is 3%.
2) If you want to dilute your stock, you need to dilute by 9.8 moles/liter divided by 0.88 moles/liter or by a factor of 11.1.
So, to make 1 liter, you need 1/11.1 liters of stock = 90 ml of stock, with the remainder, 910 ml, water.
Concentrated hydrogen peroxide is quite hazardous. Be careful.
