Matter is everything that has MASS and takes up VOLUME (or space).
It is made up of atoms and molecules which contain mass.
The three units of mass:
gram g
kilogram kg
milligram mg
Example:
A small penny coin has a mass of 2.5g
However, the mass of the M87 black hole can be as much as 3.580056 × 1031 kg!
For a grain of sand, it is estimated to have a mass of 2.5mg.
