38. what is the expected boiling point of a solution prepared by dissolving 6.37 g of sodium iodide (nal) in 48.6 g of water (h 0)? k'b (ater)-0.512"cm a) 0.90°c d) 103.26"c b) 100.45°c e) none of the above c) 100.90°c

c) 100.90°C

Explanation:

Elevation in boiling point is given by:

= elevation in boiling point

i= vant hoff factor = 2 (for NaI[/tex]

= boiling point constant =

m= molality  

Weight of solvent i kg =48.6 g= 0.0486kg

Thus the boiling point of the solution will be .

i do not get it   at all

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
