Question

What is the osmotic pressure of a 0.850M solution of glucose at 245K?

Use R=0.08206L atmmol K for the gas constant.
Report your answer using three significant figures.

Answer 1

Answer: 3.97 ATM

Explanation: The osmotic pressure, π, of a solution can be calculated using the equation:

π = i * R * T

where i is the van't Hoff factor, R is the gas constant, and T is the temperature in Kelvin.

For a 0.850 M solution of glucose, i = 2 (glucose is a non-electrolyte and has two particles per molecule).

So,

π = 2 * 0.08206 * 245

π = 3.97 atm

Thus, the osmotic pressure of a 0.850 M solution of glucose at 245K is approximately 3.97 atm.
