Milhouse massed a copper cylinder multiple times. his data is listed below. the "correct" mass of the cylinder had been previously determined to be 27.20 grams. desrcibe the accuracy and precision of the milhouses measurements. weighing 1 - 25.01weighing 2 - 25.22weighing 3 - 25.23weighing 4 - 25.19(part 2) refer to the data above. what was the percent error on milhouses first weighing? percent error = l experimental value - accepted value l / accepted value x 100%
