HELP: In this lab, it is not necessary to calibrate the volume of a drop from a Beral pipet, so long as you use the same Beral pipet for all titrations and you handle it consistently. A solution that contains 3.0 x 10^-5 mol of oxalic acid requires 24 drops of permanganate ion solution to reach the endpoint of the titration. What is the chemical amount of permanganate ion per drop?
