Question:
Which one of the following is the standard for atomic mass?
Which one of the following is the standard for atomic mass?
Show Hint
The standard for atomic mass is based on the carbon-12 isotope, which is defined to have a mass of 12 amu.
Updated On: Jan 15, 2026
- \(^{12}_6C\)
- \(^{16}_8O\)
- \(^{1}_1H\)
- \(^{14}_6C\)
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The atomic mass unit is defined using the carbon-12 isotope (\(^{12}_6C\)) as the reference. This isotope is assigned a mass of exactly 12 atomic mass units.
