Question 9

Iron(III) sulfate is an industrial coagulant widely used in the treatment of municipal and industrial wastewater to precipitate dissolved impurities.

Calculate the relative formula mass ( $M_r$ ) of anhydrous iron(III) sulfate, $Fe2(SO4)3\text{Fe}_2(\text{SO}_4)_3$ .

Relative atomic masses ( $A_r$ ):

Iron (Fe) = 56
Sulfur (S) = 32
Oxygen (O) = 16
