A piece of metal ore weighs 9.25 g. when a student places it into a graduated cylinder containing water, the liquid level rises from 21.25 ml to 26.47 ml. what is the density of the ore?

Answer :

Density is a physical property which describes the mass of a substance per unit of volume of the substance. It is expressed as Density = m / V and it has units like g/cm^3. We calculate as follows:

Density = m/V = 9.25 g / (26.47 mL - 21.25 mL) = 1.77 g / mL
