Question

la formula empirica de un compuesto de ch si el peso molecular es de 130gr ¿cual es la formula verdadera?

Answer 1

FE: CH

Mm DE LA FE
C: 1 x 12 =  12 g/mol
H:  1  x  1 = 1 g/mol
``````````````````````````````
 Mm = 13 g/mol

n = M molar del compuesto
      ````````````````````````````````
         M molar FE

n = 130 g/mol
     ````````````````
         13 g/mol

n = 10

FM: (CH)n = (CH)10 = C10H10 (Ciclodecapentaeno)
