A saturated solution of

\mathrm{PbF_2}\,(s)

25\,^{\circ}\text{C}

is prepared by dissolving

0.64\,\text{g}

of the salt in exactly

500\,\text{mL}

of water. The molar mass of

\mathrm{PbF_2}

245\,\text{g}\,\text{mol}^{-1}

. Calculate the solubility–product constant

K_{sp}

for

\mathrm{PbF_2}

25\,^{\circ}\text{C}
