Question

Por favor quien me puede ayudar en esta pregunta se lo agradeceria demasiado

Answer 1

a.   

C : 7.79 g / 12 g/mol = 0.65 mol

Cl: 92.21 g / 35.4 g/mol = 2.60 mol

Dividir cada elemento entre el menor de los resultados

C: 0.65 mol / 0.65 mol = 1

Cl: 2.60 mol / 0.65 mol = 4

FE: CCl4

Mm FE

C: 1 x 12 = 12 g/mol

Cl: 4 x 35.4 = 141.6g/mol

``````````````````````````
       Mm = 153.6 g/mol

n = 154 g/mol / 153.6 g/mol
n = 1
FM = (CCl4)1 = CCl4

b.

C : 10.13 g / 12 g/mol = 0.84416  mol

Cl: 89.87 g / 35.4 g/mol = 2.5387  mol

Dividir cada elemento entre el menor de los resultados

C: 0.84416 mol / 0.84416 mol = 1

Cl: 2.5387 mol / 0.84416 mol = 3

FE: CCl3

Mm FE

C: 1 x 12 = 12 g/mol

Cl: 3 x 35.4 = 106.2 g/mol

``````````````````````````
       Mm = 118.2 g/mol

n = 237 g/mol / 118.2 g/mol
n = 2
FM = (CCl3)2 = C2Cl6

c.
C : 25.26 g / 12 g/mol = 2.105  mol

Cl: 74.74 g / 35.4 g/mol = 2.111 mol

Dividir cada elemento entre el menor de los resultados

C: 2.105 mol / 2.105 mol = 1

Cl: 2.111 mol / 2.105 mol = 1

FE: CCl

Mm FE

C: 1 x 12 = 12 g/mol

Cl:  x 35.4 = 35.4 g/mol

``````````````````````````
       Mm = 47.4 g/mol

n =285 g/mol / 47.4 g/mol
n = 6
FM = (CCl3)6 = C6Cl18

d.
C : 11.25 g / 12 g/mol = 0.9375  mol

Cl: 88.75 g / 35.4 g/mol = 2.507 mol

Dividir cada elemento entre el menor de los resultados

C: 0.9375 mol / 0.9375 mol = 1 x 5 = 5

Cl: 2.507 mol / 0.9375 mol = 2.6 x 5 = 12

FE: C5Cl12

Mm FE

C: 5 x 12 = 60 g/mol

Cl: 12 x 35.4 = 424.8 g/mol

``````````````````````````
       Mm = 484.8 g/mol

n =  320 g/mol / 484.8 g/mol
n = 1
FM = (C5Cl)1 = C5Cl12
