We’re being asked to compare the osmotic pressure of 0.10 M solution of NaCl and 0.10 M solution of KBr. We are given the molarity which we can relate to osmotic pressure.
The osmotic pressure (Π) of a solution is related to the molarity of the solution:
i = van’t Hoff factor
M = molarity of the solution (in M or mol/L)
R = gas constant (0.08206 atm • L/mol • K)
T = temperature
Is the osmotic pressure of a 0.10 M solution of NaCl greater than, less than, or equal to that of a 0.10 M solution of KBr?
