Question
(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)
