Question

A metal cube measuring 1.50 cm on a side has a mass of 38.3g. Will this cube float or sink in mercury: your calculations must support your answer.

Answer 1

Calculate the density of the metal and see if it is less that that of mercury. The density of mercury should be looked up. It is about 13.6 g/cm^3, as I recall.

If the density of the metal is less than 13.6 g/cm^3, it wil float.

Answer 2

38.3/1.50
