Question

How is the unit of the atomic mass unit (amu) currently defined?

Select the correct answer below:

The mass of a typical carbon atom is defined as 12 amu.

The mass of a typical hydrogen atom is defined as 1.98 amu.

The mass of a typical oxygen atom is defined as 15.999 amu.

The mass of a typical helium atom is defined as 4.01 atm.

Answer 1

Answer #1

amu (atomic mass unit) definition :- It is defined as the 1/12th part of one atom of carbon - 12.

i.e.

amu(atomic mass unit) = 1/12 × (mass of one atom of Carbon -12).

Hence correct option is The mass of a typical carbon atom is defined as 12 amu.
