Explicație:
ms= 58,5 g sol. NaCl , c= 10%
AgNO3
m AgCl
-se afla md sol. de NaCl
md= c.ms :100
md= 10 . 58,5 : 100=5,85 g NaCl
5,85g xg
NaCl + AgNO3 = AgCl + NaNO3
58,5g 143,5 g
x= 5,85 . 143,5 : 58,5=14,35 g AgCl
n= 14,35g : 143,5g/moli=0,1 moli AgCl
MNaCl= 23+35,5=58,5-------> 58,5g/moli
MAgC 108 + 35,5=143,5------->143,5g/moli
