olubility pro duct (K_{sp}) of saturated PbCl_2 in water is 1.8 \times 10^{-4} mol^3 dm^{-9}. What is the concentration of Pb^{2+} in the solution?

Correct Answer is : (0.45×10−4)13moldm−3

(0.45 \times 10^{-4}) ^{1/3} mol dm^{-3}

(1.8 \times 10^{-4}) ^{1/3} mol dm^{-3}

(0.9 \times 10^{-4}) ^{1/3} mol dm^{-3}

(2.0 \times 10^{-4}) ^{1/3} mol dm^{-3}

(2.45 \times 10^{-4}) ^{1/3} mol dm^{-3}
