Answer 1

Răspuns:

Explicație:

MAl2(SO4)3= 2.27 + 3 .32 + 12.16=342--------> 342g/moli

342g Al2(SO4)3-------------96g S

300g----------------------------------x

x= 300 . 96 : 342=84,21 g S

MAl2S3=2.27 + 3. 32=150------150g/moli

150gAl2S3------------96gS

500g---------------------ygS

y=500.96 : 150=320g S
