You use the percentage as the mass of the Carbon etc, providing it is 100%, then find the moles and use the mole ratio.

Then, find the weight of the empirical formula.

Divide the mass of the molecular by the empirical, then multiply the empirical by the number you got (so, say if it is 6, you multiply the empirical, say CH20, by 6 and that would get you C6H12O6)
