How many grams will a single oxygen atom weigh? Or, if you think like a lawyer, you might prefer the official SI definition: The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon 12. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. Plugging that figure into the above equation would look like this: 10.811 = g/mole. The mass of the oxygen atom will be 4/3 greater (from Example \(\PageIndex{1}\)): \[ \left( \dfrac{4}{3} \right) 1.99 \times 10^{23} \, g = 2.66 \times 10^{23} \, g \text{ (per oxygen atom)} \nonumber\].
