Question: how to calculate moles of oh- in saturated solution?
Answer: 0.05 M * 0.0206 L= 0.001 7) Moles of OH - in saturated solution (mol)= moles of HCl added= 0.001 8) [OH - ], equilibrium (mol/L)= moles of OH - in saturated solution / volume of saturated solution  0.001 mol / 0.025 L= 0.04 9) Molar solubility of Ca(OH) 2 with added CaCl 2 (mol/L)= molar concentration of OH - in ...
