what is simple formula and molecular formula?
I've never heard the expression "simple formula" used before but I presume you are talking about the difference between the empirical formula and the molecular formula. The empirical formula of a compound is the one with the lowest molar ratio of each atom in the molecule.
As an example, most carbohydrates have the empirical formula of CH2O. All molecular formulas have a single factor multiplied by the ratios of 1:2:1 for C:H:O.
Ribose is a 5 carbon sugar and has a molecular formula of 5*(CH2O) = C5H10O5.
Glucose is a 6 carbon sugar and has a molecular formula of 6*(CH2O) = C6H12O6.
