Las feromonas son compuestos que secretan las hembras de muchas especies de insectos para atraer a los machos?

1. calcular moles

C : 80.

78 g / 12 g / mol = 6.

73

H : 13.

56 g / 1 g / mol = 13.

56 mol

O : 5.

66 g / 16 g / mol = 0.

35 mol

2.

Dividir cada uno entre el menor de los resultados

C : 6.

73 mol / 0.

35 mol = 19

H : 13.

56 mol / 0.

35 mol = 38

O : 0.

35 mol / 0.

35 mol = 1

3.

FE : C19H38O

4.

Mm de la feromona

C : 19 x 12 = 228 g / mol

H : 38 x 1 = 38 g / mol

O : 1 x 16 = 16 g / mol

Punto congelación = 5.

50 ºC

ΔTc = T2 - T1

ΔTc = 5.

50 ºC - 3.

37 ºC = 2.

13 ºC

convertir g a Kg = 8.

50 / 1000 = 0.

0085 Kg

Pc del benceno = 5.

12 ºC / m

ΔTc = Kc x g sto x 1000 despejar Mm ````````````````````````` Mm x Kg svte

Mm = 5.

12 ºC / m x 1.
