If the solubility product constant $K_{sp}$ of ${\text{AgIO}}_3$ at a given temperature is $1.0\times 10^{-8}$, what is the mass of ${\text{AgIO}}_3$ contained in $100\text{mL}$ of its saturated solution? (Molar mass of ${\text{AgIO}}_3=283\text{g/mol}$)

1. A
   $28.3\times 10^{-2}\text{g}$
2. B
   $2.83\times 10^{-3}\text{g}$
3. C
   $1.0\times 10^{-7}\text{g}$
4. D
   $1.0\times 10^{-4}\text{g}$
