Mineral "A" is a gray metallic mineral with cubic cleavage (3 planes of cleavage at right angles). Its hardness is 2.5; streak is gray to dark gray. Its mass is 29.5 g, and its volume is 3.5 cm3. What is its specific gravity?a) 1.00b) 3.12c) 8.43d) 15.99

Answer :

batolisis

Answer:

8.43 ( C )

Explanation:

GIVEN  data:

hardness = 2.5

mass = 29.5 g

volume = 3.5 cm^3

specific gravity = density of mineral / density of water

density of mineral = mass / volume = 29.5 / 3.5 = 8.43

density of water = 1

therefore specific gravity of Mineral " A " = 8.43 / 1 =  8.43

Note : The density of the Mineral is the same as the specific gravity of the mineral.
