The following data were obtained in order to determine the density of cylindrical metal bar: Height (cm) Diameter (cm) Mass (g) Trial 1 6.50 1.25 46.683 Trial 2 6.45 1.26 46.332 Calculate the average density of the metal bar. In the following calculations on this data, show the formula used, the substituted numbers and the result. Trial 3 6.44 1.22 47.014 b) Calculate the percent relative average deviation of the measurements. c) If the accepted value for the density of the bar is 6.70 g/cm³, what is the % relative error? d) Are these measurements more precise or more accurate? Explain. e) What is the purpose of repetition in measurements?
