What is the atomic mass, in atomic mass units (amu), of 12vC?

• A. 11.00000000
• B. 12.00000000
• C. 13.00000000
• D. 14.00000000

Answer: (B)

The atomic mass of an isotope is determined by the total number of protons and neutrons in its nucleus, measured in atomic mass units (amu). For the isotope \(^{12}\text{C}\), which is the most abundant stable carbon isotope, the atomic number is 6, indicating it has 6 protons. Since it is denoted as \(^{12}\text{C}\), this indicates that the total nucleon count (protons + neutrons) is 12. Therefore, \(^{12}\text{C}\) has 6 neutrons (12 total nucleons - 6 protons = 6 neutrons). This leads to an atomic mass of 12.00000000 amu, which reflects the simple sum of the protons and neutrons. The isotopic notation provides accurate information regarding the mass without any significant inclusion of mass defects or binding energy effects for such a stable configuration. Thus, the atomic mass of \(^{12}\text{C}\) is firmly established as 12.00000000 amu.
