How many liters of 20 Volume H2O2 will contain one mole of hydrogen peroxide?
20-vol is 6% w/v of hydrogen peroxide i.e. 6g in 100mL. so we can find the concentration;
6g/(34) = 0.176mol in 100mL
in 1liter = 0.176molx10 = 1.76mol
Molarity = 1.76mol/L
the question asks for how many liters for one mole so;
1L = 1.76mol
xL = 1mole
xL = 1/1.76 = 0.568L
hope that helps..
