4.74 g of an inorganic compound contains 0.39g of K, 0.27 g of Al, 1.92 g of \(\mathrm{SO_4}\) radicals and 2.16 g of water. If molar mass of the compound is \(948 \mathrm{~g} \mathrm{~mol}^{-1},\) the molecular formula of the inorganic compound is:
1.
\(\mathrm{{KAl}({SO}_4)_2 \cdot 12 {H}_2 {O}}\)
2.
\(\mathrm{{K}_2 {Al}_2({SO}_4)_6 \cdot 12 {H}_2 {O}}\)
3.
\(\mathrm{{K}_2 {SO}_4 \cdot {Al}_2({SO}_4)_3 \cdot24 {H}_2 {O}}\)
4.
\(\mathrm{{K}_2 {SO}_6 \cdot {Al}_2({SO}_4)_3 \cdot12 {H}_2 {O}}\)
