How many grams of BaF2 will disslove?

Question

How many grams of BaF2 will disslove in 0.487 L of a 0.104 M NaF solution ?


Ksp = 1.80e−7

Answer 1

Ksp=[Ba2+] X [F-]^2

but [F-] = 0.104 M from the NaF

Putting that into the expression for Ksp will let you determine the molar solubility of BaF2 in that solution. From the molar concentration of Ba2+ and the molar mass of BaF2, you can calculate the mass that will dissolve in the given volume of the solution.
