Answer 1

density is useful in determining the purity of a substance

Answer 2

The property that is useful in determining the purity of a substance is density.

• The density of a substance can be regarded as one of its signature properties that helps to identify if the given sample is a pure substance or not.
• It is because the value of density is fixed for substances and can be calculated by dividing the given mass of the substance by its volume.
• This calculated value is then compared with the theoretical value to determine its purity.
