In a sautrated solution of the sparingly soluble strong electrolyte AgIO₃ (Molecular mass = 283) the equilibrium which sets in is
AgIO_3(s) $$\leftrightharpoons$$ Ag⁺(aq) + $$IO_3^-$$
If the solubility product constant K_sp of AgIO₃ at a given temperature is 1.0 $$\times$$10⁻⁸, what is the mass of AgIO₃ contained in 100 ml of its saturated solution?
