The solubility product constant for Mg(OH)2(s) is 1.2 x 10-, Calculate the solubility of magnesium hydroxide in mol/L and in g/L 3. The concentration of Pb2+ ions and of CO-ions in a saturated aq 1.8 x 10-M. (a) Determine Ksp of PbCOs. (b) Calculate its solubility in ueous solution of PbCO3 is g/L. and in g/100 ml. at 4. Determine the molar solubility of AgCI in (a) pure water and (b) 0.10 M NaCl(aq). The Kup of AgCl is 1.8 x 10-10 164-

Explanation / Answer

1)

Moles of KNO3 = volume of KNO3 (L) x molarity of KNO3

                         = (100.0 mLx (1 L/1000 mL)) x 0.10 M

                        = 0.1000 L x ( 0.10 mol/L)

                        = 0.010 mol

Mass of KNO3 = moles of KNO3 x molar mass of KNO3

                        = 0.010 mol x (101 g/mol)

                        = 1.01 g

So, the mass of KNO3 required is 1.01 g.
