Answer:

The correct answer is -7.429 bars.

Explanation:

The solute potential inside the cell is calculated by the formula = -iCRT

Here, i refers to the number of ions, C refers to the concentration of solute, R refers to the gas constant, and T is the temperature (K)

The concentration within the cell of the plant is 0.15 M for NaCl, i = 2, R = 0.0831 and T = 298 K or 25 degree C.

Solute potential = - (2 0.15 0.0831 * 298) = -7.429 bar

The way at which the water will diffuse if the cell is placed into the 0.1M NaCl solution is: -7.43 bars.

Using this formula

Solute potential (Ψs) = –iCRT

Where:

i =ionization constant=2 because NaCl forms 2 ions

C =Molar concentration= 0.15 mole/liter

R =Pressure constant = 0.0831 liter bar/mole K

T =Temperature in degrees Kelvin = 273 + °C of solution =273 +25°C=298K

Let plug in the formula

Solute potential (Ψs)=- (2)(0.15mole/liter)(0.0831 liters bars/mole-K)(298 K)

Solute potential (Ψs) = - 7.43 bars

Solute potential (Ψs) = 0 + (-7.43 bars)

Solute potential (Ψs) = -7.43 bars

Inconclusion the way at which the water will diffuse if the cell is placed into the 0.1M NaCl solution is: -7.43 bars.
