Atomic mass of carbon is:

The atomic mass of carbon is approximately 12.01 atomic mass units (amu). This value represents the average mass of carbon atoms, taking into account the natural abundance of its isotopes.

Understanding Carbon Isotopes

Carbon has several isotopes, with the most common being:

• Carbon-12: The most abundant isotope, making up about 98.9% of carbon found in nature.
• Carbon-13: A stable isotope that accounts for about 1.1% of natural carbon.
• Carbon-14: A radioactive isotope used in dating ancient organic materials.

Importance of Atomic Mass

The atomic mass is crucial in chemistry as it helps in calculating the molar mass of compounds and understanding reactions involving carbon-based substances.
