Question

Si se tienen 216g de plata cuantas moles de óxido de plata se podrian producir (Ag:108g/mol;O:16g/mol)

A:1
B:2
C:3
D:4

Answer 1

n = masa / Mm

Mm Ag2O=

Ag =  2 x 108 = 216 g/mol
  O =1 x 16 = 16 g/mol
``````````````````````````````````````
       Mm = 232 g/mol

n = 216 g / 232 g/mol

n= 0.931 mol de plata
