The osmotic pressure, Π, of a solution of glucose is 34.2 atm . Find the molarity of the solution at 298 K. Express the molarity to three significant figures and include the appropriate units.

Solutions

Expert Solution

We know that osmotic pressure, Π = CRT

Where C = concentration = molarity = ?

R = gas constant = 0.0821 L.atm / (mol-K)

T = Temperature = 298 K

Π = osmotic pressure = 34.2 atm

Plug the values we get C = Π / (RT)

= 34.2 / ( 0.0821 x 298)

= 1.39 M

Therefore the molarity of the solution is 1.39 M
