your mom is the atomic weight of a carbonate
Carbon's atomic relative atomic mass is roughly 12 and oxygen's roughly 16. CO2 therefore is 12 + (16 * 2 ) = 44 units. So the relative _molecular_ (it can't be atomic as CO2 isn't an atom) mass of carbon dioxide is 44 units.
The atomic weight of carbon on the periodic table is 12.0107.
Florine has a greater Atomic Weight because Carbon has a Atomic Weight of 12 amu (atomic mass units) while Florine has a Atomic Weight of 19.
The atomic number is: 6. The atomic weight is 12.011
Why carbon is taken as standard value for atomic weight
Carbon dioxide is a molecular compound with the formula CO2
carbon 12
Diamonds are pure carbon and its atomic weight is 12. It has 6 protons and 6 neutrons.

Carbon's atomic mass is ~12.0107. All of those decimals at the end tell us that there is more than one isotope of carbon. If you round the number, you will find the most common isotope of carbon. (Carbon12)IUPAC recommend in this case the expression atomic weight, not atomic mass.The atomic weight of carbon (IUPAC Table, 2009) is [12,0096; 12,0116]. This mean that the atomic weight is variable between the above mentioned limits, depending on the type of the sample.
Gold has a heavier atomic weight than oxygen. Gold's atomic weight is approximately 197, while oxygen's atomic weight is around 16.
