The relationship between osmotic pressure at 273 K when 10 g glucose (...
Explanation:
Given Data:
- Osmotic pressure at 273 K when 10 g glucose (P1), 10 g urea (P2), and 10 g sucrose (P3) are dissolved in 250 ml of water.
Understanding Osmotic Pressure:
- Osmotic pressure is the pressure required to prevent the flow of solvent across a semipermeable membrane.
Calculating Osmotic Pressure:
- Osmotic pressure is directly proportional to the concentration of the solute particles.
- Glucose, urea, and sucrose all will dissociate into one particle each in solution, so the concentration of solute particles is the same for all three substances.
Comparing Osmotic Pressure:
- When comparing P1, P2, and P3, the order of osmotic pressure will depend only on the nature of the solute particles and not on their specific identity.
- Therefore, the relationship between osmotic pressure for P1, P2, and P3 will be based on the order in which the solutes are presented.
Conclusion:
- The correct relationship between osmotic pressure at 273 K for 10 g glucose (P1), 10 g urea (P2), and 10 g sucrose (P3) dissolved in 250 ml of water is P2 (urea) P1 (glucose) P3 (sucrose).
