Answer:

#Al_2(SO_4)_3#

Explanation:

#Al^(+3)+SO_4^-2##Al_2(SO_4)_3#

To get this you would have to balance the charges between the anion and metal cation.

Do this by finding the least common multiple between the parts. In this case it turns out to be 6. Therefore we need 2 moles of #Al^(+3)# and 3 moles of #SO_4^-2# to balance the charges.
