The solute potential (Ψs) is a measure of the potential energy of a solution, and it is related to the concentration of solutes in the solution. The solute potential can be calculated using the following equation:
Ψs = -iCRT
Where i is the ionization constant, C is the concentration of solutes in moles per liter, R is the gas constant (8.314 J/mol K), and T is the temperature in Kelvin.
It is not possible to calculate the solute potential without knowing the temperature in kelvin, since T is part of the equation. If you don't know the temperature, you can't calculate solute potential.
