What 2 properties of minerals can be expressed in numbers?
Two properties of minerals that can be expressed in numbers are hardness and specific gravity. Hardness is usually determined using the Mohs scale and is expressed as a number between 1 (softest) and 10 (hardest). Specific gravity is the ratio of a mineral's density compared to the density of water and is expressed as a number.
