Question

The volume of a metal rod was determined to be 38.6 mL. It’s mass was found to be 400.3 grams when measured with a platform balance. Would measuring the mass on an analytical balance improve the accuracy of the density determination? Justify your answer on the basis of significant digits.

Answer 1

volume of the metal   = 38.6ml

mass of the metal       = 400.3g

density of metal      = mass of metal/volume of metal

                                = 400.3g/38.6ml

                                 = 10.4g/ml
