Question:
Dimethylglyoxime [DMG, (CH3CNOH)2] is used as a reagent to precipitate nickel ion. Assume that 53.0 g of DMG has been dissolved in 525 g of ethanol (C2H5OH).
(a) What is the mole fraction of DMG?
(b) What is the molality of the solution?
(c) What is the vapor pressure of the ethanol over the solution at ethanol’s normal boiling point of 78.4°C?
(d) What is the boiling point of the solution?
(DMG does not produce ions in solution.)
(Kbp for ethanol = +1.22°C/m)
