Answer to Question #320092 in General Chemistry for Thel

Question

If you use 5.76mol of sodium fluoride (NaF) and dissolved this into 3.62 kg of water, what will be the change in the boiling point of your solution. Assume the Kb of water is 0.51°C/m.

Answer 1

∆T_b= iK_bm

m= 5.76÷3.62= 1.5912

i= 2

∆T_b=2×0.51×1.5912

=1.62^oc

The boiling point is elevated by 1.62^oc
