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
152 g ----- 100 %
96 g ----- x
x = 63.15 % C
ACETATO DE ISOPENTILO (C7H14O2)
H: 14 x 1 = 14 g/mol
O: 2 x 16 = 32 g/mol
Mm = 130 g/mol
130 g ----- 100 %
x = 64.6 % C
