The osmotic pressure (π) can be calculated using the formula π = iMRT, where i is the van't Hoff factor (1 for sucrose, a non-electrolyte), M is the molarity (0.25 M), R is the gas constant (0.0821 L.atm/K.mol), and T is the temperature in Kelvin (37°C = 310 K). Substituting these values gives π = (1)(0.25)(0.0821)(310) = 6.4 atm.
