Dear student
Formula unit mass of Al2
(SO4
)33=(2× Atomic mass of Al)+(3×Mass of S)+(12× Mass of O)
=2×27 u+3×32 u+12×16 u
=342 u
Thanks

(iiFormula unit mass of any compound is the sum of atomic masses of all atoms in the formula of that compound. Formula unit mass of Al2(SO4)3
Atomic mass of Al = 27 × 2 = 54 u
Atomic mass of S = 32 × 3 = 96 u
Atomic mass of O = 16 × 12 = 192 u
Formula unit mass = 54 + 96 + 192 = 342 u. Hence, Formula unit mass of Al2(SO4)3 is 342.
