Question

A piece of metal (mass = 18.300 g) is placed in 11.00 mL of chloroform (d = 1.498 g/mL) in a 25-mL graduated cylinder. The chloroform level increases to 15.46 mL. The best value for density of this metal from these data is

Answer 1

volume of the metal = volume increased - initial volume

                             = 15.46 - 11.00

                             = 4.46 mL

mass of the metal = 18.30 g

density = mass / volume

           = 18.30 / 4.46

           = 4.10 g / mL

density of the metal = 4.10 g / mL
