250 g H 2 SO 4 completely reacted with aluminum? 2AI(s) + 32504(aq)- AI2 (504) 3(aq) + 3H 2 (9)
0.85g
450g
290g
870g

290 g of aluminium sulphate is produced.

Explanation:

To calculate the moles :

The balanced chemical reaction is:

According to stoichiometry :

3 moles of produce  = 1 mole of

Thus 2.55 moles of will require=  of

Mass of

Thus 290 g of aluminium sulphate is produced.
