oxygen = 1 amu is half the mass of a carbon-12 atom. It's safe to say, in imprecise calculations, that both neutrons and protons are 1 amu. The mass of an Oxygen atom is not just the mass of the nucleus but also the mass of the electrons too
carbon dioxide =After finding the atomic mass for each element multiply each by the subscript in the chemical formula. To find the molecular weight of CO2, add these numbers up (make sure to multiply before adding!). The units of molecular weight are grams/mole or g/mol
