This scale is a chart of relative hardness of the various minerals
Coal, as an organic sedimentary rock, is not determined to have a hardness on the Mohs scale of mineral hardness.
No. The Mohs scale only lists minerals. Coal is a sedimentary or metamorphic rock, depending on the variety.
Moh's scale is a HARDNESS scale, not a HARNESS scale.
Extremely hard about 9.5 on Mohs' scale
Aluminum Oxide is roughly 8.5 - 9.0 on the hardness scale.

Peridot is around 6.5 to 7 on the mohs scale.

Friedrich Mohs is famous for creating the Mohs scale of mineral hardness. He formulated a scale of one to ten and assigned each mineral a value. This eventually became the basis for the Mohs scale.
