WebJun 2, 2024 · One mole of carbon is 6.022 x 10 23 atoms of carbon ( Avogadro's number ). This relation is then used to 'convert' a carbon atom to grams by the ratio: mass of 1 atom / 1 atom = mass of a mole of atoms / 6.022 x 10 23 atoms. Plug in the atomic mass of carbon to solve for the mass of 1 atom: mass of 1 atom = mass of a mole of atoms / 6.022 x 10 23.

WebNov 5, 2024 · Use the periodic table to determine the atomic mass of each element in the molecule. Multiply each element's atomic mass by the number of atoms of that element in the molecule. This number is represented by the subscript next to the element symbol in the molecular formula. Add these values together for each different atom in the molecule. WebAtomic mass is most conveniently described by the atomic mass unit, which is 1/12 of the mass of a carbon-12 atom. This means that each proton and each neutron contribute 1 amu to the mass of an atom, which makes it very easy to calculate. You can also use this to account for different isotopes. side effects of ultomiris
