3) What is the osmotic pressure of a solution formed by dissolving 25.0 mg of aspirin (C 9 H 8 O 4 ), a non- electrolyte, in enough water to make 0.250 L of solution at 25 °C? A) 0.0136 atm B) 1.14×10 −3 atm C) 13.6 atm D) 2.45 atm E) 1.38 atm 2 1 1 2 1 1 ln a E k k R T T / a E RT k Ae t ½ = 0.693/ k [X( aq)]= K H P X P x,stn = χ x P ° x Δ T b = m k b Δ T f = m k f Π = MRT P x = χ x P total R = 0.08206 (atm∙L)/(mol∙K) = 8.314 J/(mol∙K) 1 atm = 760 torr = 760 mm Hg
