The molecular formula of glucose:
C₆H₁₂O₆
The concentration of the solution in mass percent is 60%.
<h3>What is the mass percent?</h3>
The concentration of a substance can be expressed in mass percent. This refers to the percentage of the solute that is contained in the solution.
Thus we can write;
Mass percent = Mass of solute/ Mass of solution * 100/1
Mass percent = 1.5kg/1.5kg + 1 Kg * 100/1
Mass percent = 60%
Hence, the concentration of the solution in mass percent is 60%.

Explanation:
Hello,
In this case, for the mole fraction of methanol we use the formula:

Thus, we compute the moles of both water (molar mass 18 g/mol) and methanol (molar mass 32 g/mol):

Hence, mole fraction is:

Next, mass percent is:

And the molality, considering the mass of water in kg (0.185 kg):
