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

Answer:

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.

Answer 2

Answer:

180 g of H2O2

Explanation:

3.0 % of 6.00 kg = 3.00/100 * 6.00 kg = 0.18 kg H2O2  

0.18 kg = 0.18 kg * 1000 g/kg = 180 g
