Answer:

The answer is provided below

Explanation:

To determine the metal is gold we will use the following steps

  • Calculate the density of the Metal
  • Take the density of the pure gold
  • Compare both densities

Take a full water container

Place the metal in the container

Collect the water that spills out due to the placement of the metal

measure the mass of collected water.

Calculate the value in terms of the density of water, it will be the volume of metal.

Calculate the mass of the metal

Use the following formula to calculate the density of the metal

Density = Mass / Volume

Now compre the resulted density to the density of pure gold.
