What is the formula to determine the mass of tin II fluoride, SnF2, that is created when 45 g of nitrogen trifluoride, NF3, is reacted?

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.
