In order to find molecular formula from empirical formula, one needs to know the molar mass of the molecular formula. Then you simply divide the molar mass of the molecular formula by the molar mass of the empirical formula to find out how many empirical formulae are in the molecular formula. Then you multiply the subscripts in the empirical formula by that number.

How do you calculate the molecular weight and the uncertainty of the molecular weight of a unknown solute using propagated error?
To calculate the molecular weight, you need to perform a chemical analysis to determine the elemental composition of the unknown solute. Then, using the atomic masses of the elements found, you can calculate the molecular weight by summing the atomic weights of all the atoms in the molecule. To determine the uncertainty in the molecular weight, you would need to propagate the errors in the atomic masses and the elemental composition through the calculation using the rules of error propagation.
What additional information do you need to determine the molecular formula?
To determine the molecular formula, you need the molecular weight of the compound, the empirical formula, and any information about the compound's structure or the number of atoms of each element present. Additionally, knowing the types of elements involved can also help in calculating the molecular formula accurately. If the empirical formula is known, the ratio of the empirical formula's mass to the molecular weight will help in finding the actual molecular formula.
How do you calculate molecular weight in electrophoresis?
To calculate the molecular weight of a protein in electrophoresis, you would use a standard curve generated with protein standards of known molecular weights run on the same gel. By plotting the migration distance of the standard proteins against their known molecular weights, you can then determine the molecular weight of your protein of interest based on its migration distance on the gel in comparison to the standard curve.
