Answer with explaining please I $\text{'}$m not good at this topic$11-20.$ In contrast to many salts, calcium sulfate is only par$-$

tially dissociated in aqueous solution:

$CaS{O}_4(aq)C{a}^{2+}+S{O}_4^{2-}$

$K_d=5\mathrm{.}2{10}^{-3}$

The solubility$-$product constant for $CaS{O}_4$ is $2\mathrm{.}6$

${10}^{-5}.$ Calculate the solubility of $CaS{O}_4$ in $($a$)$ water

and $($b$)0\mathrm{.}0100MN{a}_{2}S{O}_4.$ In addition, calculate the

percent of undissociated $CaS{O}_4$ in each solution.
