A group of biology students weighed several potato cubes and placed them in open beakers containing various sucrose solutions at 30°C. The following day, the students weighed the potato cubes again and
calculated the differences in mass.
It was determined that solute potential equilibrium was reached at 0.35 M.
Solute potential of a solution: U.
- CRT
. ¿= ionization constant (1.0 for sucrose)
C=molar concentration
• R = pressure constant (0.0831 L. bar mol-'. K-1)
T = temperature in Kelvin (°C of solution + 273)
What is the solute potential of the potato cubes?
