Hi guys, this is an Osmotic Pressure question
-If you have a solution of 1L of H20 and 234 grams of NaCl, what is the Osmotic Pressure at STP (R=0.1atm/mol K)?
Well, the formula is P=M(for molarity)*R*T
If I plug in the values I get 109.2 (when using 273K as my standard Temperature). When I use 298 for my standard temp I get 119.2. None of those answers are correct. Topscore has 218.4 atm as the right answer. I don't understand why? I guess my questions is when should I use 273K as my standard temp and when 298K as my standard temp. In addition, why in the world is the answer 218.4K????
