Part 3 3.1. Calculate the molarity of your initial KMnO4 solution as well as t uncertainty due to the tolerance of the glassware (assume a tolerance of 0.1 mL, for Class A vol Make sure to propagate this uncertainty for calculated the concentrations a solutions. Also calculate the concentration of K+ and MnOs in parts-per-million (pp he two diluted solu tions including the umetric flasks) and uncertainty of the diluted by mass for your initial , solution as well as the two diluted solutions including the uncertainty (see Harris textbook for guidance on this if you need it). ked to acquire an absorb ance value for your initial, undiluted KMn0 3.2. Why do you think you were not as solution? 3.3. How does the magnitude and wavelength of maximum absorbance of the KMnO, solution change as you dilute it? 3.4. What does Beers Law tell you should happen to the absorbance of your solution if you dilute it as was done here? Do your experimental results agree with what is predicted by Beers Law? If you diluted the concentration by a factor of 12, how much would you expect the absorbance to increase or decrease?
