Question 17

Easy

Iron(III) sulfate, $Fe2(SO4)3\text{Fe}_2(\text{SO}_4)_3$ , is widely used in water treatment as a coagulant to remove suspended solids from drinking water and industrial wastewater.

What is the relative formula mass ( $MrM_{\text{r}}$ ) of anhydrous iron(III) sulfate?

Relative atomic masses ( $ArA_{\text{r}}$ ): $O=16.0\text{O} = 16.0$ , $S=32.1\text{S} = 32.1$ , $Fe=55.8\text{Fe} = 55.8$

$271.9$

$335.7$

$344.1$

$399.9$
