1. calcular moles
C: 24.49 g / 12 g/mol = 2.040 mol
H: 4.08 g / 1 g/mol = 4.08 mol
Cl: 72.43 g / 35.5 g/mol = 2.040 mol
2. dividi entre el menor de los resultados
C: 2.040 mol / 2.040 mol = 1
H: 4.08 mol / 2.040 mol = 2
Cl: 2.040 mol / 2.040 mol = 1
3. Fórmula empírica: CH2Cl
4. Calcular Mm de la fórmula empírica
C: 1 x 12 = 12 g/mol
H: 1 x 2 = 2 g/mol
Cl: 1 x 35.5 = 35.5 g/mol
``````````````````````````````````````````````````
Mm = 49.5 g/mol
5. calcular n = Mm compuesto / Mm Fórmula empírica
n = 98 g/mol / 49.5 g/mol
n = 2
6. Fórmula molecular: (CH2Cl)2 = C2H4Cl2
