Mass density = rho = M/V; where M is mass (in kg) and V (in m^3) is the volume the mass is packed into.
There is also weight density = Rho = W/V = Mg/V = rho g; where g = 9.81 m/sec^2 acceleration due to gravity at Earth's surface. Weight (in Newtons) = Mg.
So density is simply mass or weight divided by the volume that mass or weight is crammed into.

The mass is how much an object weighs, usually in grams. The density is the mass divided by the volume, usually written in g/ml or whichever volume measurement you are using.

mass is a property of an object which opposes
any change in it's state of rest or state of motion
(it is quantity of material)
density is quantity of matter per unit volume.

Mass is the amount of matter. (i.e. 1 billion atoms)
Density is how tightly packed it is. (i.e. number of atoms per cubic centimeter)
