Solution: You wish to increase the boiling point of water to 105°C by adding lithium fluoride to 125. mL of water. How much lithium fluoride must you add to the water? Assume the density of the water was 1.00 g

Problem

You wish to increase the boiling point of water to 105°C by adding lithium fluoride to 125. mL of water. How much lithium fluoride must you add to the water? Assume the density of the water was 1.00 g/mL when the lithium fluoride was added; the Kb for water is 0.512°C/m.

a) 15.8 g

b) 31.6 g

c) 63.3 g

d) 45.9 g

e) Impossible, the boiling point decreases with the addition of lithium fluoride.
