Percent Composition Empirical And Molecular Formulas Bundle By Determining percent composition from formula mass. percent composition is also useful for evaluating the relative abundance of a given element in different compounds of known formulas. as one example, consider the common nitrogen containing fertilizers ammonia (nh 3), ammonium nitrate (nh 4 no 3), and urea (ch 4 n 2 o). the element nitrogen is.

Therefore, the subscripts (moles) in the empirical formula must be multiplied by two to obtain the molecular formula: molecular formula = 2 x empirical formula. 2 x c 3 h 4 o 3 = c 6 h 8 o 6. calculate the molar mass of this formula to make sure it matches the one given in the problem: m (c 6 h 8 o 6) = 6 x 12.0 8 x 1.00 6 x 16.0 = 176 g. 4) write the empirical formula: so 2. 5) compute the "empirical formula weight" (i'll use efw from now on): 32 16 16 = 64. 6) divide the molecule weight by the "efw:" 64.07 64 = 1. 7) use the scaling factor computed just above to determine the molecular formula: so 2 times 1 gives so 2 for the molecular formula.
