What is the Atomic Mass of Carbon?

Atomic Mass of Carbon is  .

A) 10

B) 11

C) 12

D) 13

Answer:

Option B) 12 is correct.

Explanation:

Atomic Mass of any substance is the sum of the number of protons and the number of neutrons in the nucleus of that atom.

For Carbon,

• Number of Protons = 6
• Number of Neutrons = 6

Thus,

Atomic Mass of Carbon = 6 + 6 = 12

In absolute terms, the average atomic mass of carbon is 12.011 amu. It is calculated taking into account all the isotopes of Carbon.
