Answer: 0.100 m
Explanation:
Elevation in boiling point is given by:
= Elevation in boiling point
i= vant hoff factor
= boiling point constant
m= molality
1. For 0.100 m
, i= 3 as it is a electrolyte and dissociate to give 3 ions. and concentration of ions will be
2. For 0.100 m
, i= 2 as it is a electrolyte and dissociate to give 2 ions, concentration of ions will be
3. For 0.200 m
, i= 1 as it is a non electrolyte and does not dissociate, concentration of ions will be
4. For 0.060 m
, i= 4 as it is a electrolyte and dissociate to give 4 ions. and concentration of ions will be
Thus as concentration of solute is highest for , the elevation in boiling point is highest and thus has the highest boiling point.
