Answer 1

The Mohs scale of mineral hardness is a qualitative scale used to determine the hardness of minerals.

Step-by-step explanation:

The Mohs scale of mineral hardness is a qualitative scale developed by Frederich Mohs in 1822. It is used to determine the hardness of minerals based on their ability to resist scratching or abrasion. The scale consists of 10 minerals, with diamond being the hardest mineral with a rating of 10. By comparing the unknown mineral's hardness to the minerals on the scale, we can identify the unknown mineral.

Answer 2

Mass: 981.0 g

Density: 5.61 g/cm^3

Hardness: 2.5-3

Unknown Mineral: chalcocite
