A sample of the material halite measures 3.18 cm long by 3.06 cm wide by 2.79 cm high and has a mass of 58.75 g. What is the its specific gravity?

Specific gravity = Density of an object/Density of water

Density = Mass/Volume

For the current scenario;

Density of halite = mass / (l*w*h) = 58.75 / (3.18*3.06*2.79) = 58.75/27.148932 = 2.164 g/cm^3

Density of water ≈ 1000 kg/m^3 = 1 g/cm^3

Therefore,

Specific density of halite = 2.164 g/cm^3 / 1 g/cm^3 = 2.164
