Question

A metal has a mass of 8.7 grams and a volume of 3.2mL is it metal gold ?

Answer 1

The metal is not gold.

Step-by-step explanation:

• It is known that the density of gold (d) = 19.32 g/mL.

• We need to calculate the density of the given data of the metal and compare with the theoretical density value:

Density (d) = mass/volume

∴ d of metal = mass/volume = (8.7 g)/(3.2 mL) = 2.72 g/mL.

So, the metal is not gold.
