A dalton is a unit of measurement used for what?

• A. Length
• B. Time
• C. Mass
• D. Volume

Answer: (C)

A dalton is a unit of measurement specifically used to express the mass of atomic and molecular particles. It is defined as one-twelfth the mass of an unbound neutral atom of carbon-12 in its ground state, which makes it particularly useful in the fields of chemistry and biology for discussing the sizes and masses of molecules and proteins. The use of the dalton simplifies calculations regarding molecular mass when dealing with very small values, such as those found in atomic and molecular scales. In contrast, the other options—length, time, and volume—represent different dimensions of measurement and are not associated with the concept of mass, thereby confirming that mass is the appropriate context for the dalton unit.
