The density of hematite ore is <u>4.78 g/cm³</u>.
Let the mass of the ore be m₁ , the volume of the flask <em>V</em>, total mass of water and ore M, mass of water be m₂, density of ore ρ₁ and the density of water be ρ₂.
Density of a substance is defined as the mass per unit volume.
The mass of water in the flask is given by,

Calculate the volume V₂ of the water in the flask.

Calculate the volume V₁occupied by the ore in the flask.
1 ml is equivalent to 1 cm³.
Calculate the density of the ore.

The density of the hematite ore is found to be 4.78 g/.cm³
