Reaction 1 (10 mL undiluted 1.0% IKI and 5 mL undiluted 3% H₂O₂)

Reaction 2 (10 mL diluted 0.5% IKI and 5 ml undiluted 3% H₂O₂)

Reaction 3 (10 mL undiluted 1.0% IKI and 5 mL diluted 2.25% H₂O₂)

13. Answer the following. (

a) How many moles of H2O2 are present in Reactions 1 and 2? Show your work (include units). Hint: The initial H2O2 solution is 3% m/v (mass/volume) hydrogen peroxide in water. That means that 3 g H2O2 are present in every 100 mL of solution. Hint: The molecular weight of H2O2 is 34.0147 g/mol.

(b) What is the total volume of each reaction in liters?

(c) What is the [H2O2] present in Reactions 1 and 2 in units of molarity (M)? Show your work (include units).

(d) What is the [H2O2] present in Reaction 3 in units of molarity (M)? Show your work (include units). Hint: The H2O2 solution is 2.25% m/v (mass/volume) hydrogen peroxide in water for Reaction 3. Hint: You are repeating 13a – 13c for the 2.25% solution to find the answer here.
