What is the density of an unknown metal that has a mass of 1158 g and a volume of 20 mL?

Answer 1

Density is calculated by dividing mass by volume. One mL is the same as 1 cm3.

D = m / V

= 1158 / 20

= 57.9 g/cm3

You can now use a reference table to determine what the metal might be, or if you know what the metal is you can use a reference table of metal densities to compare the values. If your value, 57.9 g/cm3 is different from the reference value then your piece of metal is not pure.

I am assuming that this metal is imaginary as its density is almost 3 times that of gold and more than 5 times that of lead.

Answer 2

The density of the unknown metal can be calculated by dividing the mass (1158 g) by the volume (20 mL), which gives a density of 57.9 g/mL.
