A student measures the mass of a metal bar as 57.21 g. the student fills a graduated cylinder with water and determines the volume of water to be 53.70 mL. The student places the metal bar into the graduated cylinder and records the new volume as 58.80 mL. Calculate the density of the metal bar.

The density of the metal bar is 11.217 g / ml.

Explanation:

The density of the metal bar can be found by using the ratio of mass and volume.

Given,

The weight of the metal bar is 57.21 g.

The Volume of water is 53.70 ml.

The Volume of the water and the bar is 58.80 ml.

The volume of the metal bar is 58.80 - 53.70 = 5.10 ml.

                  Density = mass / volume

                                = 57.21 / 5.1 = 11.217 g / ml.

The density of the metal bar is about 11.2 g / ml.
