Q-HOW DOES DENSITY TELL PURITY OF SUBSTANCE.

please explain according to 3 marks. Please help.

Answer 1

Answer:

Density means how tightly the molecules of any matter is combined, this help to understand purity of substance , like the density of metals are high means the molecules of metals are very tightly combine because it is solid .

whereas the density of non metals are low because the molecules of non metals are not very tight

Answer 2

Answer:

Imagine that you know the relative density of substance x. When you are a sample given that is x, you need to verify, you must calculate relative density of the sample and see if it matches the relative density of X.

If it does, then it's pure.

If not, it's impure.
