Question

 

Problem B (SW) What Osmotic Pressure (Pi) can be generated by a 2M sugar solution at 16oC.

(hint) use   Pi = MRT    change 16oC to K    R = .08 L Atm/mol K

Your answer should be greater that 1 ATM.. a pressure that causes the seed to burst!

Answer 1

π = MRT

M = 2 molar = 2 mol/L

R = gas constant = 0.0821 Latm/Kmol

T = temperature in K = 16 + 273 = 289K

π = (2 mol/L)(0.0821 Latm/Kmol)(289K) = 47.5 atm
