3 AgNO3 + AlCl3 ⇒3 AgCl + Al(NO3)3
Mm AgNO3 = 169,87 g/mol
AlCl3 = 133,34 g/mol
AgCl = 143,32 g/mol
calcular moles a partir de los gramos
mol AgNO3 = 4.22 g/ 169.87 g/mol = 0.0248 mol
mol AlCl3 =7.73 g/ 133.34 g/mol = 0.0579 mol
calcular moles de AgCl a partir de los moles calculados
mol AgCl = 0.0248 mol AgNO3 x 3 mol AgCl
``````````````````
3 mol AgnO3
mol AgCl3 = 0.0248
mol AgCl = 0.0579 mol AlCl3 x 2 mol AgCl
``````````````````
1 mol AlCl3
mol AgCl = 0.1158
mol = masa/Mm
masa AgCl = 0.0248 mol x 143.32 g/mol
masa AgCl = 3.55 g
