If you mean 1 molecule of Aluminium Sulfate then yes there are 17 atoms
2 aluminium, 3 sulfur and 12 oxygens
However it is rarely found as an anyhdrous (without water) salt.
It's most common form is Al2(SO4)3.16H2O which would contain 17 + (16*3) atoms = 65 atoms

Al2(SO4)3
2 Al atoms + 3 S atoms + 12 O atoms
= 17 atoms altogether

Basically if you were doing experimental molar calculations then use Al2(SO4)3.16H2O
If it is a simple pre A-level test, then use the 17 answer
