Question
An aqueous salt solution has a freezing point of -.5 degrees Celsius and causes neither swelling or shriveling of cells. The kf of water is 1.86 K kg/mol. What is the osmotic pressure that is exerted on cells when placed in pure water? (ignore differences between molarity and molality)
Answers
Use delta T = i*Kf*m and calculate m.
Then use pi = i*mRT and solve for pi
Then use pi = i*mRT and solve for pi
would i=1 and delta t=.5 deg C?
Also, if it says that the experiment was performed at 273 K, would that be the value of T in the second equation?
yes
