An experiment to determine osmosis was conducted. Russet potato cubes were placed in a solution of sucrose at a concentration of 0.308 M. The experiment was carried out at approximately 24° C. Calculate the solute potential of solution B.
To calculate the solute potential of solution B, you can use the formula:
Ψs = -iCRT
Where:
Ψs = solute potential
i = ionization constant (1 for sucrose)
C = molar concentration of the solute (0.308 M)
R = pressure constant (0.0831 L•bar/mol•K)
T = temperature in Kelvin (24°C is equal to 297 K)
Plugging in the values:
Ψs = -1 * 0.308 M * 0.0831 L•bar/mol•K * 297 K
Calculating the equation will yield the solute potential in terms of units of pressure, typically bars.
