What volume is 30 hydrogen peroxide?
30% (w/v) means: if you take 100 ml of that solution, it contains 30 g of H2O2. You should keep it at 4°C in a dark bottle.
How do you make 30 H2O2?
A 30% hydrogen peroxide solution contains 30 g in 100 ml. To prepare 3% solution you need 3g hydrogen peroxide . Hence from 30% H2O2 solution you take 10 ml and add 90ml water.
