(C) The dissociation of $Al_2(SO_4)_3$ is given by: $Al_2(SO_4)_3 \rightarrow 2Al^{+3} + 3SO_4^{-2}$ From the stoichiometry,$2 \ \text{moles of } Al^{+3}$ are produced for every $3 \ \text{moles of } SO_4^{-2}$. Given $[Al^{+3}] = 1.8 \ M$. Since the ratio of $[Al^{+3}] : [SO_4^{-2}]$ is $2 : 3$,we have: $\frac{[Al^{+3}]}{[SO_4^{-2}]} = \frac{2}{3}$ $[SO_4^{-2}] = \frac{3}{2} \times [Al^{+3}] = 1.5 \times 1.8 \ M = 2.7 \ M$.
