Use the appropriate values from your spreadsheet calculations to a) calculate [(m)/m ]2 , the mass contribution to the random error in the density. b) calculate [(V)/V ]2 , the volume contribution to the random error in the density. c) Which contributes more to the random error in the density, the mass or the volume measurements? d) State one way that the experimental procedure could be revised to reduce the random error due to the larger contribution without reducing the accuracy of the measurements
