d............ atomic mass unit

Answer 2

Answer:

(d) atomic mass unit

Explanation:

• There are numerous variations on the concept of mass in chemistry. The mass of an atom expressed in unified atomic mass units is frequently thought to be the definition of atomic mass (u).
• Because chemistry was the first science to study the same physical objects at both the macroscopic and microscopic levels, the term "atomic mass" was coined historically. The isotope distribution further adds to the complexity of the situation.
• Most mass measurements of pure substances at the macroscopic level pertain to an isotope mixture. This indicates that these mixes are not pure from a physical standpoint.
