By determining the molecular mass, then dividing the molecular mass by the formula mass of the empirical formula to determine by what integer the subscripts in the empirical formula must be multiplied to produce the molecular formula with the experimentally determined molecular mass.

∙ 14y agoIf you know the molar mass of the compound, you have to calculate the mass of the empirical formula and divide the molar mass of the compound by the mass of the empirical formula in order to find the ratio between the molecular formula and the empirical formula. Then multiply all the atoms by this ratio to find the molecular formula!

∙ 10y agoBy first determining the approximate molecular mass of the compound in question, usually by measurements of osmotic pressure, freezing point depression, or some other colligative property that depends on the number of molecules present. The approximate molecular mass of the substance in question is then calculated from the colligative property measurements, and this value is then divided by gram molecular mass corresponding to the empirical formula. The nearest integer to the resulting quotient is then applied as a factor by which to multiply each subscript of the empirical formula to yield the molecular formula.

What are the steps in writing a molecular compound?
First U have to write the symbols of elements that form the compound, forexample if we want to write the chemical formula of magnesium chloride:1. Mg Cl2. we have to write the valence of each element below itMg Cl2 1then, we switch the valences of each oneso, the chemical formula is going to be:MgCl2

How do you find the molecular and empirical formulas?
There is no easy answer to this question. First, it depends what information you have to start with. Do you have the name? Do you know what elements are found in the substance?If you are given the name of the molecule, you can often find the molecular structure of that compound by simply using the Google search engine online and searching for the name. It is often give you the answer! There are certain compounds that you should be familiar with also. Also, there is a set of official rules that determine the name of a specific compound, so that if you have the formula, you can name it correctly, and if you have the name, you can determine the formula. Unfortunately, many chemicals also have common names that do not follow these rules, and you just have to memorize those, or look them up with Google.See the Related Questions and Web Links to the left for some information about how compounds are named and how to go from a formula to a name and vice versa.
