Granite doesn't have a single Mohs hardness. It's a composite rock made up of different minerals, each with its own hardness. The minerals in granite typically range in hardness from 6 to 7 on the Mohs scale.

Here's a breakdown:

* Quartz: The most common mineral in granite, with a hardness of 7.

* Feldspar: Another common mineral in granite, with a hardness of 6 (though some varieties can reach 6.5).

* Mica: A softer mineral found in granite, with a hardness of 2-3.

Therefore, granite's overall hardness varies depending on the proportions of its constituent minerals. You can't assign a single Mohs hardness value to it.
