Which would be the hardness of a mineral that can be scratched by a penny but not a fingernail?
A mineral that can be scratched by a penny (which has a hardness of about 3.5 on the Mohs scale) but not by a fingernail (which has a hardness of about 2.5 to 3) would have a hardness between 3 and 3.5. This means the mineral's hardness is likely around 3.2 to 3.4, indicating it is softer than the penny but harder than a fingernail. Examples of minerals that fit this description could include calcite or gypsum, depending on their specific characteristics.
