A chemist studies the composition of matter and its properties such as density, acidity, size, and shape. They carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists use this knowledge to learn the composition, and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes.
The mathematics required for becoming a chemist includes but is not limited to College Algebra, Geometry, Trigonometry, Calculus I and II, and Statistics.
