How does on determine a molecular formula from the empirical formula?
molar mass over grams of elementThe above answer is somewhat correct. In order to find the molecular formula when given the empirical formula, you must first find the molar mass of the empirical formula.MOLAR MASS# atoms element A x Atomic Mass element A (Periodic Table) = mass A# atoms element B x atomic mass element B (periodic table) = mass B... etc.Add up all of the mass values found above and you have the molar mass.Then, after you have found the empirical formula's molar mass, you divide the molar mass of the molecular formula by the empirical formula's molar mass (solving for n).MOLECULAR FORMULA EQUATION: N (Empirical formula) (read as N times empirical formula) where:N = Molar mass substance---- Molar Mass emp. form.

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
What steps are used to convert an empirical formula into a molecular formula?
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.
Where does the chemical symbol of helium come from?
The symbol, He, comes from the first two letters of the element helium
Which element has the atomic nunber 1 and also comes first on the Periodic Table?
Hydrogen is the element having atomic number1 and comes first in the periodic table.
Which element of plot usually comes first?
exposition
Which symbol comes first in a chemical formula?
This depends on the type of compound. For metallic compounds, the metal comes first. For nonmetallic inorganic compounds the more electropositive element comes first. For MOST organic compounds, carbon comes first.
What critical piece of information must be known in order to determine the molecular formula?
you must know the molar mass! you need to get the empirical formula first too.
