Highest Boiling Point

Which solution has the HIGHEST boiling point? (Berkeley Review Gen Chem. Part 2, page 90, example 7.16)

A.) 0.10 moles magnesium chloride in 100 mL water

B.) 0.15 moles lithium bromide in 150 mL water

C.) 0.20 moles sodium iodide in 100 mL water

D.) 0.25 moles potassium fluoride in 150 mL water

The answer is "C'. I put "A". I used the formula for finding the increase in boiling point when solute is added to a solution: Delta Tb = kb*i*m

I calculated the (i*m) values for each of the...
