well, it would have produced 150/.45 g of O2, which is
moleO2= 150/.45*32
which means twice those moles were used in the peroxide, or
2*150/(.45*32)=2.5*Molarity
solve for molarity
If the reaction
2H2O2 →2H2O+O2
has a 45% yield, what is the molarity of the H2O2 solution if 2.5 L of this solution pro- duces 150 g of O2?
