What is a non SI-unit traditionally used by chemists?
|
Angstrom

|
Why is the kilogram an unusual base unit?
|
It contains a prefix. Generally, in forming most other SI mass units you add the prefix to (grams).
|

Density:
|
Mass per unit volume.
density = mass/volume |
|
|
Broadly, how could you describe density?
|
Simply, it expresses the concentration of mass present in a unit volume of substance.
-> Things with a low density have fewer and/or smaller atoms packed into a given space as compared to an object with a higher density. |
|
|
Who provided the basic theory that all matter (elements, compounds, mixtures) are composed of atoms?
|
British chemist John Dalton
