I need help on questions 1-2? If you can't help me on question 2, then you can help me on question 1.

DATA SUMMARY TABLES Use the table provided to fill in the measured values and observations obtained during the lab. Molarity of standard KMnO4 solution: Mass of empty flask (g) Mass of flask with sample (g) Initial buret level Final buret level Qualitative comments Trial 1 125.250 g 135.068 g 0.45 mL 41.43 mL Light pink Trial 2 125.825 g 135.201 g 0.39 mL 43.68 mL 0.1000 M Over-titrated/pink Trial 3 126.195 137.192 0.43 mL 46.79 Light pink Page 1 of 4 QUESTIONS AND CALCULATIONS For each calculation, you will be required to show detailed work steps. Make sure the number of each question is clear according to what was in the introductions and procedure document. Meaning, make sure that your use of the template doesn't mess up the numbering! 1) Determine the moles of KMnO4 required for each trial. Use Equation editor here to show all your work!
