Question

What is the amount (in g) of hydrogen peroxide (H2O2) needed to make a 6.00 kg , 3.00 % (by mass) H2O2 solution?

Answer 1

Explanation:

6% H2O2 in water = 6 g H2O2 in 100 mL water = 60 g H2O2 in 1 liter water. ... Therefore the molarity of your 6% solution is 60 g/34 g/mol = 1.765 mol in 1 liter = 1.765 M. To add 10 mmole of H202 to your reaction from this concentration of solution will require 5.67 mL of 6% H2O2.
