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.
