what is the measure if how tightly matter is packed into a givin volume of a substance
Density is a measure of how tightly the matter within it is packed together.
The more mass can be packed into a given volume, the greater the density. Alternatively, the less volume into which a given mass is packed, the greater the density.
divide its mass by its volume
It means that the molecules are packed together very tightly.
