A solution containing 0.71 g of Ca(OH)₂ (m= 74.093 g/mol) in 625 mL of water at 298.15 K, assume the solute completely dissolves. 1 atm = 760 mm Hg, R = 0.08206 (atm∙L)/(mol ∙ K).
a) Calculate the concentration (in molarity) for this Ca(OH)₂ aqueous solution.
b) Calculate the osmotic pressure of the solution in mm Hg.
