hydrogen peroxide calculation
Posted 28 January 2009 - 05:11 AM
I need a simple calculation, i.e conversion of 30% H2O2(FW 34.5) to 2mM H2O2
Is this right. molarity=%*10/FW

Molarity= (weight in grams/FW in grams)*(1000/volume in mL)
If you % is weight/volume then you can use it directly (chk the formula you gave, I think its wrong, but not sure...too tired to chk it ), if its volume/volume then you need to get the weight by using density that will be given on the bottle.
Hope it helps.
