All about 30 % Hydrogen Peroxide (H2O2): Morality

1. 30g H2O2/100 g solution
2. The density of the solution is 1.11 g/cm3
3. Morality is measured in moles per liter
M = (w/mwt)x V (lit)
w = weight in grams
mt = Molecular weight
V = Volume in Liters
(D = w/V)
M = (D/Mt)x % of solution x 1000
Mt = 34.01,    % of solution = 30,  Density = 1.1 g/cm3. 
4. Hence Morality of 30 % H2O2 is 9.79 M


  1. Are you serious? "Morality" No one cares about the ethics of H2O2. The molarity or the molality would be more useful.

    1. Hilarious! I was just thinking "crap, morality? What is that in chemistry terms and how does that relate to molality?" Was about to go off and do a wiki search for morality per L :-)
