13. Mohs hardness test has a scale range of _____

1 to 10 100 to 200 1 to 1000 1 to 3000

1 to 10

Mohs hardness scale was developed by ?Frederich Mohs? in 1822, which is a chart that denotes relative hardness of various materials (1-softest to 10-hardenst). According to Mohs scale, diamond is hardest material and talc is softest material.
