Answer:
149.58 bars
Explanation:
The solute potential (ΨS) of a solution is given by:
ΨS = iCRT
Where i = ionization constant of the solution, C = molar concentration of the solution, R = pressure constant =0.0831 liter bars/mole-K, and T = temperature in Kelvin.
NaCl dissociates in water to give Na and Cl ions, hence, i = 2
T = 27 + 273 = 300 Kelvin
C = 3.0 M
ΨS = 2 x 3 x 0.0831 x 300
= 149.58 bars.
