What is the molality of a 13.82% by mass glucose solution? the molar mass of c6h12o6 is 180.16 g/mol?

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.
