Answer:

374 atoms would be present in 22 units of aluminum sulfate.

Explanation:

Formula for Aluminium Sulfate :  Al₂(SO₄)₃

Al = 2

S = 1

O = 4

(SO) = 3

∴ Number of atom in one unit is :  2 + (1+4)3 ==> 17

If there are 17 atoms in one unit, therefore;

Number of atoms in 22 units = 17 x 22

                                                = 374 atoms
