Q. 5. Define the atomic mass unit. Atomic mass unit is equal to 1/12th of mass Ans.atomic mass unit is equal to 1/12th of mass of 1 atom of carbon 12 atom ​

Answer 1

Answer:

The dalton or unified atomic mass unit is a unit of mass widely used in physics and chemistry. It is defined as 1⁄12 of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest. The atomic mass constant, denoted mᵤ is defined identically, giving mᵤ = m/12 = 1 Da.
