Question

A mineral sample has a mass of 9.882 kg and a volume of 1.22 x 10^3 cm^3. The mineral is either a sample of spahleric ( density - 4.0 g/cm3), cassiterite (density - 6.99 g/cm3), or cinnabar ( density - 8.10 g/cm3). Which one is it

Answer 1

For answering this question you need to finddensity of sample:

9.882 kg = 9882 g

D = 9882 g / 1.22 x 10^3 cm^3 = 8.10 g/cm³, so itis cinnabar
