How to Calculate Percent Abundance?

Answer

If you're referring to atomic percent in chemistry, you need to divide the number of atoms in the molecule or compound molecule by the atoms of each substance and multiply by 100. If you're calculating abundance by mass (the more likely scenario) by atomic weights. You can find atomic weights on any periodic table.
