Answer 1

1. calcular Mm del H3PO4

H: 3 x 1 = 3 g/mol

P: 1 x 30.97 = 30.97 g/mol

O: 4 X 16 = 64 g/mol

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

Mm = 97.97 g/mol

hidrógeno

97.97 g ---- 100 %

3 g ----- x

x = 3.06 % H

FÓSFORO

97.97 g ----- 100 %

30.97 g ------ x

x = 31.61 % P

Oxígeno

97.97 g ---- 100 %

64 g ------ x

x = 65.32 % O
