Given: 2KMnO4 + 5H2O2 + 3H2SO4 -> K2SO4 + 2MnSO4 + 5O2 + 8H2O
If initially 5.65 g of potassium permanganate was taken for the reaction, calculate the total mass of manganese (II) sulfate present in the solution after the completion of the reaction. What is the Potassium ion concentration of the solution (assume that the total volume of the final reaction mixture is 500 mL).
For the first part, I got 30g MnSO4 and for the second question, I got 0.404M K+. Just checking if that's right.
