Expert Answer

Step 1

According to the statement of the question, 49.9 percent Glucose aqueous solution means that in 100 g of water 49.9 g of Glucose is present.

According to Raoult’s law mole fraction of a solute is equal to the relative vapor pressure lowering. It can be written as follows:

Here,

P0 is the vapor pressure of the solvent (pure water) that is given as 375.0 mmHg

P is the vapor pressure of the solution

X is the mole fraction of the Glucose
