Question

Hardness is another physical property of minerals. The harder a mineral is, the less likely it is to be scratched. To determine a mineral’s hardness, scratch it against an object with a known hardness. You could try a penny or even your fingernail. We can measure hardness using the Mohs scale. The Mohs scale goes from 1 to 10. Minerals with a lower number are softer. Minerals with a higher number are harder. Talc has a hardness of 1, so it can be scratched very easily. Diamond has a hardness of 10. No other mineral can scratch it. A penny has a hardness of 3.5, and glass has a hardness between 5.5 and 6.

Which of the following could be the Mohs scale number for a mineral that is harder than talc, but softer than a penny?

A
7

0.3
