Chemistry is the study of matter and the changes that matter undergoes.

Pure chemistry is chemistry done for the sake of gaining new information. An example would be any type of research, such as an analytical chemist determining the composition of an unknown compound, or a biochemist determining the chemical structure of a newly discovered virus.

Applied chemistry is chemistry done to improve our lives. It does not discover new information about chemistry, but makes practical use of existing chemical knowledge. An example would be manufacturing rayon or nylon (synthetic fibers) and producing clothes.

Nomenclature can be defined as the terminology of chemical compounds. It represents the basic "language of chemistry" and, just as the student who is studying French or Spanish must learn the terminology of those languages, so must the chemistry student learn the basic terminology of the discipline.

Regents Chemistry

Molecular Weight

The molecular weight of a substance is the weight in atomic mass units of all the atoms in a given formula.

An atomic mass unit is defined as 1/12 the weight of the carbon-12 isotope. The old symbol was amu, while the most correct symbol is u (a lower case letter u). NYS Chemistry will use amu.
