Mm C = 12 g/mol
H = 1 g/mol
C = 92.35 g / 12 g/mol = 7.695 mol
H = 7.7 g / 1 g / mol = 7.7 mol
dividir cada elemento entre el menor de los resultados
C = 7.695 mol / 7.695 mol = 1
H = 7.7 mol / 7.695 mol = 1
FORMULA EMPIRICA = C1H1 (CH)
MASA MOLECULAR DEL COMPUESTO
C = 1 x 12 g = 12 g/mol
H = 1 x 1 g = 1 g/mol

formula molecular = (C1H1)n
(C1H1)6 = C6H6
FM = C6H6
H = 1 g/mol
C = 92.35 g / 12 g/mol = 7.695 mol
H = 7.7 g / 1 g / mol = 7.7 mol
