What is the definition of atomic mass number?
Atomic Mass is the sum of the number of protons and neutrons in the atom, plus any additional mass conferred by electrons. (Since electrons are roughly 1/1837th of a proton's mass, this additional mass is minuscule and is only represented in atoms that have atomic numbers at the higher end of the table.) It should be an integer/whole number.The reason that most elements have a number with decimals for their atomic mass numbers on the Periodic Table is because those numbers average all of the different isotopes of the element in proportion to how common they are. For example, Oxygen has an atomic mass number of 15.999 since the overwhelming majority of oxygens have 8 protons and 8 neutrons for a total atomic mass number of 16, but there are some rare oxygens with 8 protons and 7 neutrons for a total atomic mass number of 15. Once these are averaged, since the 16s are much more common, the resulting number is 15.999.
Can explain how to get the molecular of mass of CO2?
To determine the molecular mass of CO2, you need to add the atomic masses of the constituent atoms in one molecule of CO2. Carbon has an atomic mass of 12.01, and each oxygen atom has an atomic mass of 16.00. The molecular mass of CO2 is calculated as (1 * carbon atomic mass) + (2 * oxygen atomic mass) = 12.01 + 2(16.00) = 44.01 g/mol.

What is oxygens weight?
The atomic weight of oxygen is approximately 16.00 grams per mole.
If oxygens atomic number is 8 then what does the oxgen atom have?
An oxygen atom with atomic number 8 has 8 electrons in its electronic configuration. It has 8 protons in the nucleus, giving it an overall neutral charge. Oxygen typically forms two covalent bonds with other elements to achieve a stable octet configuration.
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
