Answer:
Out of the following properties, the least useful for identifying a sample of calcite would be its color. Calcite is a mineral that can be found in a variety of colors, including white, gray, black, brown, red, orange, yellow, green, and blue. This means that its color is not a reliable indicator of its identity.
Other properties that can be used to identify calcite include its hardness (3 on the Mohs scale), specific gravity (2.71), and cleavage (rhombohedral). Calcite is also a birefringent mineral, which means that it splits light into two rays of different polarization when viewed through a polarizing filter.
