A 0.060 m C 6 H 12 O 6 (aq) solution (glucose) is separated from a 0.040

Question:

A 0.060 m C6H12O6(aq) solution (glucose) is separated from a 0.040 m CO(NH2)2(aq) solution (urea) by a semipermeable membrane at 25°C. For both compounds, i = 1. 

(a) Which solution has the higher osmotic pressure?

(b) Which solution becomes more dilute with the passage of H2O molecules through the membrane?

(c) To which solution should an external pressure be applied to maintain an equilibrium flow of H2O molecules across the membrane?

(d) What external pressure (in atm) should be applied in part (c)?
