The uncertainty (standard deviation) in a single buret reading for a 50 ml buret is about +/- 0.02 ml. Two readings (initial volume and final volume) are required to deliver a specified volume or titrant. For a delivered volume of 32.65ml, compute the uncertainty in the volume of titrant delivered. Report your result as the relative standard deviation in parts per thousand, to the nearest .1ppt
