Answer:
The molality is 
Explanation:
Let's start defining the molality.

We also know that in terms of masses :
(I)
Finally, we define the mass percent as :

Using the data of the mass percent we find that :

⇒
(II)
We know that the molar mass of glucose is 
Therefore, if we use the mass of 1 mole of glucose (
) in (II) ⇒


Now, if we use the equation (I) :


⇒ 
We find that 1 mole of glucose (
of glucose) are combined with
of solvent to obtain
of solution which is a 13.82% by mass glucose solution.
If we want to find the molality, we can replaced all the data in the equation of molality :


We use 1 mol of glucose in the equation (which corresponds to 180.16 g of glucose)
The letter ''m'' is the unit of molality.
