A rock occupies a volume of 20 cm3 and has a mass of 100 g. Find the density of this rock.

The density of rock = 5 g/cm³

Given

Volume of rock=20 cm³

Mass = 100 g

Required

Density

Solution

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

The unit of density can be expressed in g/cm³ or kg/m³  

Density formula:  

ρ = density  

m = mass  

v = volume  

Input given values in formula

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
