\text{CaF}_2

K_{sp}=1.5\times10^{-10}

. Determine the molar solubility of

\text{CaF}_2

in a

1.0\times10^{-4}\,\text{M}

NaF solution. (Do not assume that

2x

is negligible relative to

1.0\times10^{-4}\,\text{M}

.) (a)

1.5\times10^{-6}\,\text{M}

(b)

3.0\times10^{-4}\,\text{M}

(c)

1.5\times10^{-2}\,\text{M}

(d)

8.7\times10^{-6}\,\text{M}
