A gold-colored pebble is found in a stream. Its mass is 23.2 mg and its volume is 1.20 mm3. What is its density in grams per cub
Lilit [14]

Answer:

The density in g/cm3 is 1.9333(put a line above the 3's to show it's repeating).

And no it is not gold because the density of gold in g/cm3 is 19.3.

Explanation:

Divide the mass by the volume in order to get an object's Density.

so, 23.2 divided by 1.20 mm3

=1.93333333 g/cm3

That is the density then you find out the density of gold in grams per cubic centimeter, that is 19.3 g/cm3

For example, gold will always have a density of 19.3 g/cm3; if a mineral has a density other than that, it isn't gold.
