Which of these solutes raises the boiling point of water the most? ionic lithium chloride (licl) ionic sodium chloride (nacl) molecular sucrose (c12h22o11) ionic sodium phosphate (na3po4) ionic magnesium bromide (mgbr2)

ionic sodium phosphate

Explanation:

The formula used:

= change in boiling point

i = Van'T Hoff factor  

= boiling point constant

m = molality

1.  For

i= 2 as it is ionic and dissociate to give 2 ions.

2. For

i= 2 as it is ionic and dissociate to give 2 ions.

3. For

, i= 1 as it is a non electrolyte and does not dissociate.

4. For

, i= 4 as it is ionic and dissociate to give 4 ions.

5.  For

, i= 3 as it is ionic and dissociate to give 3 ions.

Thus as vant hoff factor is highest for , the boiling point will be raised most.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
