Answer 2

Answer:

The osmotic pressure of 0.1 M urea solution at 27°C is 2.46 atmK⁻¹.

Explanation:

What is osmotic pressure (π)?

• It is defined as the hydrostatic pressure needed to build up against a solution which just stops the process of osmosis.
• Alternatively, it may also be defined as the pressure which must be applied to the concentrated solution in order to stop osmosis.

Types of solutions on the basis of osmotic pressure:

1. Hypertonic solution: When two solutions are compared, the one with higher osmotic pressure is termed as hypertonic.
2. Hypotonic solution: When two solutions are compared, the one with lower osmotic pressure is termed as hypotonic.
3. Isotonic solution: Two molecules having the same osmotic pressures at the same temperature.

Calculation:

Mathematically, the osmotic pressure of a solution may be calculated with the help of the formula:

π = CRT, where,

• π = osmotic pressure
• C = concentration of solutes in the solvent in moles
• R = universal gas constant
• T = temperature

Given that,

C = 0.1 M; R = 0.082 Latm/mol/K; T = 27°C = (27 + 273) K = 300 K

∴ By the problem,

π = 0.1 × 0.082 × 300

or, π = 2.46 atmK⁻¹
