1. Hydrogen peroxide is a powerful oxidizing agent that is used in concentrated solution in rocket fuels and dilute solution as a hair bleach. A 30% by mass of H2O2 solution has a density of 1.11g/ml. Calculate it's morality, mole fraction of H2O2, and molarity. 2. You have a stock solution of 14.8M NH3. How many milliliters of this solution should you dilute to make 100 mL of 0.250 MH3? 3. If you take a 10mL portion of the stock solution and dilute it to a total volume of 0.250L, what will be the concentration of the final solution? 4. Given the reaction: H2SO4 (aq) + 2NaOH(aq) 2H2O(I) + Na2SO4(AQ) What is the concentration of the NaOH solution if 45.7 mL of 0.5MH2SO4 is used to neutralized a 20mL NaOH solution?
