What is the osmotic pressure (in atm) of a 1.81 M aqueous solution of urea [(NH2)2CO] at 24.5°C?

What is the osmotic pressure of a 1.81 M aqueous solution of urea at 24.5°C?

The osmotic pressure of a 1.81 M aqueous solution of urea at 24.5°C is approximately 3.63 atm.

Calculation of Osmotic Pressure

Osmotic Pressure Formula: π = MRT Osmotic pressure (π) is calculated using the formula where M is the molarity of the solution, R is the ideal gas constant (0.0821 L·atm/(mol·K)), and T is the temperature in Kelvin. First, we convert the temperature from Celsius to Kelvin: T = 24.5 + 273.15 = 297.65 K Then, we calculate the osmotic pressure: π = (1.81 M) * (0.0821 L·atm/(mol·K)) * (297.65 K) = 3.63 atm Therefore, the osmotic pressure of the 1.81 M aqueous solution of urea at 24.5°C is approximately 3.63 atm. Osmotic pressure is an important property used to understand the behavior of solutions and their effects on biological systems.
