Maximus Martinez · Answer 1

The solute potential is expressed in the formula P = - iCRT, where i = the ionization constant, C = the molar concentration, R = the pressure constant (R = 0.0831 liter * bars/mole * K), and T = the temperature in K (273 + °C). At atmospheric pressure and 25°C has an osmotic potential - A 0.15 M NaCl solution contains 2 ions, Na + and Cl - (where sucrose stays as one particle); therefore i = 2, and the water potential = - 7.4 bars.

Water will move into the cell by osmosis from 0.1 to 0.15.
