A) \[{{10}^{9}}{{\left( \frac{W}{M} \right)}^{5}}\]
B) \[{{10}^{7}}{{\left( \frac{W}{M} \right)}^{5}}\]
C) \[{{10}^{5}}{{\left( \frac{W}{M} \right)}^{5}}\]
D) \[{{10}^{3}}{{\left( \frac{W}{M} \right)}^{5}}\]
Correct Answer: C
Solution :
[b] Solubility \[S=\frac{10\,W}{M}\frac{mol}{lit}\] \[{{K}_{sp}}\text{ }of\,C{{a}_{3}}{{\left( P{{O}_{4}} \right)}_{2}}=108\text{ }{{S}^{5}}\] \[=108\times {{10}^{5}}{{\left( \frac{W}{M} \right)}^{5}}\]
