Question

Composicion porcentual de Ga (NO2)3

Answer 1

Respuesta:

CALCULAR MASA MOLECULAR

Al = 1 x 27 = 27 g/mol

O = 3 x 16 = 48 g/mol

H = 3 x 1 = 3 g/mol

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

        Mm = 78 g/mol

Aluminio

78 g ----- 100 %

27 g -----    x

x = 34,31 %

oxigeno

78 g ----- 100 %

48 g -----    x

x = 61,53 %

hidrógeno

78 g ----- 100 %

  3 g -----    x

x = 3.85 %
