Help on units of concentration please?

[Doug]

Apologies for asking what may seem like a dumb question...

I have aquired a quantity of H2O2 which is stated as being "100 Volumes". I haven't used volumes for a long time, am I correct in thinking that one volume is equivalent to 1ml per litre?

If so, would that make my H2O2 a 10% solution by volume?

Thanks

A concentration of 100 volumes is about 30%.

"Volumes" is the measure given to how many litres of oxygen is released by one litre of the H2O2 solution.

Excellent, thank you very much.
