2. (a) In an osmosis cell, one side of its cell was filled with a solution which was made by dissolving 1.04 g of an unknown compound in 175.0 mL of solution at 25 °C. The osmotic pressure of this solution is 1.93 atm. Briefly explain why the osmotic pressure occurred. Determine the concentration of the solution, molar mass and molecular formula of the unknown compound which contains carbon, hydrogen and oxygen if the combustion of 24.02 g of this compound produced 28.16 g CO2 and 8.64 g H2O. (R = 0.0821 L atm mol·' K'', RAM: C = 12.0, H =1.0, O = 16.0)
