What is the formula for osmotic pressure?
Sorry, I guess I should've been a bit more clear; I did get the osmotic pressure using nRT and converted atm to torr resulting in 223 torr.
My issue is getting the boiling and freezing points for the solution. I tried using The Freezing Point Colligative Property;
detlaTf=Kf m and detltaTb =Kb m. The book says I should get Tf=-0.021 and Tb=100.006. I'm not sure what I'm missing but I'm not getting those answers.
