Choose the aqueous solution that has the highest boiling point. these are all solutions of nonvolatile solutes and you should assume ideal van't hoff factors where applicable. a. 0.100 m k2so4 b. 0.100 m lino3 c. 0.200 m c3h8o3 d. 0.060 m na3po4 e. they all have the same boiling point.

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.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
