Question
using the given values for trial 1, how would you find the mass of pure liquid H2O2?
![The process that occurs in this titration is a redox reaction that occurs in an acidic solution, via the balanced
equation shown below. You will need the coefficients from this reaction for your calculations below.
H₂SO4 (aq) + 2 KMnO4 (aq) + 5 H₂O2 (1)→ 5 O2 (g) + 2 MnSO4 (aq) + K2SO4 (aq) + 8 H₂O (1)
Calculation for Mass Percentage of pure liquid H₂O2 in store-bought H₂O2 solution:
Using the volume and molarity of KMnO4 used in the trial, calculate the mass of
pure liquid H₂O2 in grams present in the titration. You will need the coefficients
from the balanced reaction shown above.

Because the store-bought hydrogen peroxide solution is mostly water, the density of
the solution is assumed to be the same as water, 1.00 g/mL. Using your exact
volume of store-bought H₂O2 solution, determine the mass of store-bought H₂O2
solution. You do not need to show any work for this step.
Using the mass of pure liquid H₂O2 calculated and the mass of store-bought H₂O₂
solution, determine the mass percentage of pure H₂O2 in the solution.
