Answer 2

Answer:

Molar mass  of  K₂SO₄.Al₂(SO₄)₃.24H₂O = 948 g/mol

Explanation:

Name of K₂SO₄.Al₂(SO₄)₃.24H₂O = Alum (Potash Alum)

Formula = K₂SO₄.Al₂(SO₄)₃.24H₂O

atomic mass of potassium, K = 39g/mol

atomic mass of sulphur, S = 32g/mol

​atomic mass of aluminium, Al = 27g/mol

atomic mass of oxygen, O = 16g/mol

​atomic mass of hydrogen, H = 1g/mol

​

Now molecular mass of  K2SO4.Al2(SO4)3.24.H2O​ = 2×(atomic mass of K + atomic mass of Al) + 4 × (molecular mass of SO4) + 24×( molecular mass of H2O)

molecular mass of  K2SO4.Al2(SO4)3.24.H2O​ = 2×(39+27) + 4× 96 + 24 × 18

                                                                   = 948g/mol
