Do you mean to find the molar ratio of Fe(NO3)3 and Ti-isopropoxide in 1%, 5%, and 10% dopant? In that case you should know the molecular weight of your reactants, calculate how much much mole you have taken during your experiment and get the ratio. It is quite simple.

What are these numbers 1%, 5%, 10%? Are they the mole % or mass%? Or something else. It needs more clarification. But as first step you need the molecular weight of each component
