To determine the empirical formula of a compound, you need to find the ratio of the elements present in the compound. This can be done by analyzing the mass percentages of each element in the compound and converting them into moles. Then, divide the moles of each element by the smallest number of moles to find the simplest whole number ratio. This ratio represents the empirical formula of the compound.

To find the molecular formula from the empirical formula (C3H5O) and molar mass, you need to calculate the molar mass of the empirical formula. Then, divide the molar mass of the unknown compound by the molar mass of the empirical formula to get a ratio. Finally, multiply the subscripts in the empirical formula (C3H5O) by this ratio to determine the molecular formula of the unknown compound.
What additional information do you need to determine the molecular formula?
