Calculate the solubility of PbF2 in water at . You'll find data in the ALEKS Data tab. Round your answer to significant digits.

0.5 g/L.

Explanation:

Hello,

In this case, for this solubility problem, we can write for the lead (II) fluoride:

And the equilibrium expression is:

Whereas Ksp of lead (II) fluoride is 3.3x10⁻⁸. In such a way, we can write the equilibrium expression in terms of the molar solubility as follows:

Hence, solving for we find:

Moreover, since the molar mass of lead (II) fluoride is 245.2 g/mol, the solubility turns out:

Best regards.
