Molarity for this solution is: 3.40 mol/L

Explanation:

Osmotic pressure is the colligative property which formula is:

π = M. R. T

83.1 atm = M. 0.082 L. atm/mol. K. 298K

83.1 atm / (0.082 L. atm/mol. K. 298K) = M

As you see all the units are cancelled, except for mol/L which means certainly Molarity

83.1 atm / (0.082 L. atm/mol. K. 298K) = 3.40 mol/L
