molarity = moles per liter

M = m/l

Calculate the molecular weight of H2O2 (~34g/l).
6% H2O2 ==> 60g H2O2 per liter of solution (1 liter of H20 has a mass of 1000g, so 6% of 1000)
Calculate the number of moles of H2O2 (60g/(34g/l))
Divide by the number of liters you have (1) to get moles per liter, molarity.
