The K sp for barium fluoride, BaF2, is 2.45 × 10-5. What is the molar solubility of barium fluoride?

The molar solubility of barium fluoride is 0.0183 moles/liter.

Explanation:

The equation for the reaction will be as follows:

By Stoichiometry,

1 mole of gives 2 moles of and 1 mole of

Thus if solubility of is s moles/liter, solubility of  is s moles/liter and solubility of is 2s moles/liter

Therefore,  

Thus the molar solubility of barium fluoride is 0.0183 moles/liter.

can you attach a picture of the lettuce? : )

the correct answer would be d. hope this !
