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)

Why can measuring osmotic pressure help you find the molar mass of a solute? Assume that the solute is not an electrolyte. Choose the best answer. Choose one: Osmotic pressure depends on the hydrogen bonding capacity of the solute. Osmotic pressure depends on the molarity of the solute. Osmotic pressure depends on the mass of the solute. Osmotic pressure depends on the chemical identity of the solute. The osmotic pressure inside human cells is about 8 atm. at 20.85 °C. My advisor once misread a protocol I gave him, and without thinking washed the cells with a solution of 1.88 M NaCl. He immediately swore. What happened to the cells? Choose one: O The cells absorbed water and exploded. The high concentration of salt made the water boil at room temperature. The high concentration of salt made the water freeze at room temperature. The cells lost their water to the solution and collapsed.
