AI overview
A dalton is a unit of measurement used to express the mass of very tiny objects like atoms and molecules, defined as one-twelfth of the mass of a carbon-12 atom. It matters because scientists need a standard way to compare and describe the weights of individual atoms and molecules, which is essential for chemistry, biology, and physics research.
