Question

calcula la composición centesimal del sulfato de amonio, (NH4)2SO4

Answer 1

Mm
N: 2 x 14 = 28 g/mol
H: 8 x 1 = 8 g/mol
S: 1 x 32 = 32 g/mol
O: 4 x 16 = 64 g/mol
``````````````````````````````
        Mm = 132 g/mol

NITROGENO

132 g -------- 100 %
  28 g --------    x
x = 21.21 %

HIDROGENO

132 g -------- 100 %
     8 g --------    x
x = 6.06 %

AZUFRE

132 g -------- 100 %
  28 g --------    x
x = 21.21 %
