1) Two aqueous solutions are placed in a U tube (one on each side) separated by a semipermeable membrane. One solution is one liter of 0.05 M urea (a molecular solute) and the other is one liter of 0.02 M Na2SO4. Assume ideal solutions at the same temperature. i) Which solution has the higher osmotic pressure? ii) In order to stop water from flowing, pressure must be applied to which side of the tube? A) i) urea, ii) urea B)...
