Question

Alum K2SO4 Al2(SO4)324H2O
Atomic mass

Answer 1

"Answer:

Formula = K₂SO₄.Al₂(SO₄)₃.24H₂O

Atomic  mass  of  elements:-

K₂ = 39×2 = 78

(SO₄)₃= 3(32 + 16×4) = 96

Al₂ = 27×2 = 54

24 H₂O = 24 × 18 = 432

Molar mass  of  K₂SO₄.Al₂(SO₄)₃.24H₂O = 78+96+54+288+432

                                                                   = 948 g/mol
