22. A solution is prepared by dissolving 6.00 g of an unknown nonelectrolyte in enough water to make 1.00 L of solution. The osmotic pressure of this solution is 0.750 atm at 25.0°C. What is the molecular weight of the unknown solute (R - 0.0821 L'atm/K mol)?
Calculate the pH of a solution that is prepared by dissolving 0.740 mol of hypochlorous acid (HCIO, Ka = 3.00x10-8) and 0.254 mol of hydrofluoric acid (HF, K, = 6.60*10-4) in water and diluting to 4.50 L. Also, calculate the equilibrium concentrations of HCIO, CIO-, HF, and F. Do not make an approximation unless the initial acid concentration is greater than 1000 ~ Kg. (Hint: The pH will be determined by the stronger acid of this pair.) pH = [HCIO]...
