Key Takeaways: Atomic Mass Versus Mass Number Relative Atomic Mass or Atomic Weight Relative atomic mass or atomic weight is the average atomic mass divided by one unified atomic unit. So, average atomic weight of carbon is 12.011 12 u ÷ 1 u = 12.011 12. 2019-12-07 · The atomic mass of carbon is 12.011.

Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2. Definitions of molecular mass, molecular weight, molar mass and molar weight. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)

Carbon is one of the most important elements on Earth. It is classified as a non-metal and found in rocks, plants, and animals. You will find carbon all over the planet including gasoline, charcoal, diamonds, and plastics. More Information: Carbon: Carbonate Mineral Atomic number and mass number both are main characteristics of an atom of the element.
