Convert it.
To find the empirical formula with percentages, first convert the percentages to grams. Then divide the grams by the atomic mass of each element. Finally, simplify the ratios to find the simplest whole number ratio, which represents the empirical formula.
take any number and multilpy by 100
To find the empirical formula from percentages, convert the percentages to grams, then divide the grams by the element's molar mass to find the moles. Finally, divide the moles by the smallest number of moles to get the ratio of elements in the compound, which represents the empirical formula.
you may find graphs on google. type in images of graphs and it will come up.

Look it up in "periodic table of elements" You can find the number of a particular element by looking at the Periodic Table; you can also do this by counting the number of protons in the nucleus.
There are infinitely many bell curves and you need to have the distribution parameters to find percentages.
randomly look...
You can find this information from the periodic table.
