Question

i dont know where to begin. if someone could help me get started I would really appreciate it.

14 lect23-24 in 23 Problem 1 MAIN VERSION) The total volume of a solution of tinidazole in 5.00 kg of acetone at 25°C and 1 bar of pressure was experimentally determined and fit the following equation, where b is the molality of the tinidazole solute (in units m) v () = 1056.0 €) + 716.00 ) +6337.0 What is the partial molar volume of acetone when the volume of the total solution is 6355.0 cm? Keep five significant figures throughout your calculations. Compare that to the partial molar volume of pure acetone and state whether attractive or repulsive forces are dominating relative to the unmixed state. V = 1056.00 = = 6355cm3 dazole Eg 6305cm} = 1056.0 ( + 716() + 6337.0

Answer 1

Molality (6) = male a 0.024 .. Male = (Molality x kg) = (0.024 x 5 ) = 0.12. rolenme partial molar 6355 rolume = - 52958.33 cm3 /mole. male = 0.12 ~ 52958 cm3/male partial molare rolume of pure ace tone = 740 166 cm3 / male' Explanation of pure acetone has strong dipole - dépole attractive force but in solution state this forece decreeases.
