To find the molecular weight of the empirical formula you add up the atomic masses of each element from the periodic table. Let's say the empirical formula is C2H3 . To find the carbon you multiply 12.01 x 2 and add it to the mass of the hydrogen, 1.01 x3. The total molecular weight is 27.05 amu.

also called the simplest formula, gives the simplest whole number ratio of atoms of each element present in a compound Exp The simplest ratio for acetylene (C2H2) is 1:1. The empirical formula for acetylene is CH. For benzene (C6H6) the simplest ration is also 1:1, so the empirical formula for benzene is also CH.
