Question

If 45.0 g of C6H12O6, are dissolved in 215 g of H2O, what will be the boiling point of the resulting solution?

(Kb= 0.52oC/m)

A) 100.00oC
B) 100.22oC
C) 100.60oC
D) 112.35oC

Answer 1

C. 100.60oC

Step-by-step explanation:

Find the molality of the solution first, 1.16 m. Then, multiply by the Kb of 0.52. Then, add that number to the boiling point of pure water (100o). This is the new boiling point of the solution 100.60o.
