Calculate the osmotic pressure of a 0.195 M aqueous solution of sucrose, C12H22O11, at 37 ∘C.

Answer 1

π = iMRT

π = osmotic pressure = ?

i = van't Hoff factor = 1 for the non electrolyte sucrose

M = molarity = 0.195 M

R = gas constant = 0.0821 Latm/Kmol

T = temperature in Kelvin = 37 + 273 = 310K

π = (1)(0.195)(0.0821)(310)

π = 5.04 atm
