Asolution of water (kf=1.86 ∘c/m) and glucose freezes at − 2.75 ∘c. what is the molal concentration of glucose in this solution? assume that the freezing point of pure water is 0.00 ∘c.

Explanation:

Relation between freezing temperature and molal concentration is as follows.

The given data is as follows.

    = difference in temperature = =

            molality, (m) = ?  

Now, putting the given values into the above formula as follows.

                m =

                    =

                    = 1.48 m

Therefore, we can conclude that molal concentration of glucose in the given solution is 1.48 m.
