Take a 100 g sample, convert percent to grams.
Convert grams each to moles.
Then find the ratio as in your other problems.
Determine the mass of the empirical formula, then find (molar mass/empirical mass) = n and round to a whole numbers.
(empirical formula)<sub>n</sub> is the molecular formula. Post your work if you get stuck.
