# In a saturated solution of the sparingly soluble strong electrolyte $AgIO_3$ (Molecular mass = 283) the equilibrium which sets in is <br> $AgIO_3(s) \rightleftharpoons Ag^+ (aq) + IO_3^- (ag)$ <br> if the solubility product constant $K_{sp}$ of $AgIO_3$ at a given temperature is $1.0 \times 10^{-8}$, what is the mass of $AgIO_3$ contained in 100 mL of its saturated solution ?
( A ) $28.3 \times 10^{-2} g$
( B ) $1.0 \times 10^{-7} g$
( C ) $2.83 \times 10^{-3} g$
( D ) $1.0 \times 10^{-4} g$
