Answer 1

Benzaldehido (C7H6O )

1. CALCULAR Mm del compuesto

C: 7 x 12 = 84 g/mol

H: 6 x1 = 6 g/mol

O: 1 x 16 = 16 g/mol

`````````````````````````````````````````````

     Mm = 106 g/mol

calcular % de carbono

    106 g ----- 100 %

      84 g -----     x

         x = 79.25 % C

VAINILLINA (C8H8O3)

1. calcular Mm del compuesto

C: 8 x 12 = 96 g/mol

H: 8 x 1 = 8 g/mol

O: 3 x 16 = 48 g/mol

````````````````````````````````````````````````

        Mm = 152 g/mol

calcular % de carbono

    152 g ----- 100 %

      96 g -----     x

         x = 63.15 % C

ACETATO DE ISOPENTILO (C7H14O2)

1. calcular Mm del compuesto

C: 7 x 12 = 84 g/mol

H: 14 x 1 =  14 g/mol

O: 2 x 16 =  32 g/mol

````````````````````````````````````````````````

        Mm = 130 g/mol

calcular % de carbono

    130 g ----- 100 %

      84 g -----     x

         x = 64.6 % C
