The Ksp for NiCO3 is 6.6 x 10^-9 M. If you place 5.0 mg of NiCO3 in 1.0 L of pure water, does all the salt dissolve? If not how much salt remains undissolved?

b) If you place 50.0 mg of NiCO3 in 1.0 L of pure water, does all the salt dissolve? If not how much salt remains undissolved?

c) If you add 2.0 x 10^-5 moles of solid Na2CO3 to a 1 L saturated solution of NiCO3, how many moles of NiCO3 total will precipitate?
