Question

A sample of the mineral calcite has a volume of 15 cm³ and a mass of 40.5 g. What is the density of the calcite?A.0.37 g/cm³B.2.7 g/cm³C.55.5 g/cm³D.607.5 g/cm³

Answer 1

Given data:

Volume of calcite (V) = 15 cm³,

mass of calcite (m) = 40.5 g,

find the

            density of calcite (ρ) = ?

density is defined as " it is the amount of matter of an object in a given volume". Simply it is the ratio of matter in an object to its volume. The unit of density is kg/m³ in SI system or g/cm³ in CGS system.

Mathematically,

                         density ( ρ) = mass/volume    

                                            = m/V     g/cm³

                                            = 40.5 g/15 cm³

                                            = 2.7 g/cm³

Hence, the density of calcite is 2.7 g/cm³
