Question

1 amu is equal to
(a) 1 of O-16 (b) 1 of C-12
14 12
(c) 1 g of H₂ (d) 1.66 × 10⁻²³ kg

Answer 1

Answer:

1/12 the mass of carbon-12

Answer 2

(b) 1/12 of C-12

Explanation:

Amu is short for atomic mass unit. Atomic mass unit is defined as precisely one-twelfth (1/12) of the mass of an atom of Carbon-12. The carbon-12 (C-12) atom contains six protons and six neutrons in its nucleus. In general terms, one AMU is the average of the proton rest mass and the neutron rest mass.

Option B is the answer.
