QID 401896:
Question gives molarity and information to calculate temperature and the vant hoff factor, and asks to determine the value of osmotic pressure for a given substance. Fairly simple plug-and-play.

Text
Give the formula for osmotic pressure:
{{c1::π = iMRT}}
Extra
i = van't Hoff factor
M = molarity
R = gas constant
T = temperature in Kelvin
If you plug in moles and kelvin the answer is in atm. Other thing is that the i factor is just taking into account how many actual seperate molecules you have. So you're just trying to get how many moles of ANY nonpermeable atom do I have times RT.
