I need help calculating the solubility. thank you C. Calcium Fluoride, CaF2 (aka, Fluorite), in a solution containing 19 mg/L of LiF (aka, Griceite),with all of the LiF being dissolved into solution. Please assume that LiF dissolves such that [Li] =[F] = 7.33 x 10-4 m. After adding CaF2 to the solution and allowing it to dissolve, what are finalvalues of [Ca], [Li] and [F]?Note: you are given the concentrations of [Li] and [F] that result from dissolving LiF. Nosolubility calculation is required for dissolving LiF; just use the concentration given above.Steps:- First, write the stoichiometric equation for dissolution of CaF2 , with the solidon the left and the two ions in solution on the right, separated by a "two-way" arrow. Hint: whenCaF2 dissolves, you get 2 moles of F for every 1 mole of Ca.- Second, set up a law of mass action equation for dissolution of CaF2. There is a common ioneffect for F, so if [Ca] = x, then [F]= 2x + [FLiF], where [FLiF] is from dissolution of the…
