Is a solution weighing 120 g with a mass fraction of potassium permanganate 4% enough to oxidize

Is a solution weighing 120 g with a mass fraction of potassium permanganate 4% enough to oxidize a solution of 50 g with a mass fraction of sodium sulfite 3%, which also contains potassium hydroxide?

2KMnO4 + Na2SO3 + 2KOH = 2K2MnO4 + Na2SO4 + H2O; M (Na2SO3) = 126 g / mol; in 50 g 3% solution ν (Na2SO3) = (50 * 0.03) / 126 = 0.012 mol; For interaction with 0.012 mol Na2SO3 ν (KMnO4) = 0.012 * 2 = 0.024 mol. In 120 g of a 4% solution of KMnO4: M (KMnO4) = 158 g / mol; ν (KMnO4) = (120 * 0.04) / 158 = 0.03 mol. Since 0.03> 0.024, the KMnO4 solution is sufficient for the oxidation of Na2SO3.
Answer: not enough is wrong.
