The mole fraction of glucose in an aqueous binary solution is 0.1. The mass percentage of water in it to the nearest integer is-
Mole fraction of glucose, in
Now, lets assume we have 10 moles of solution.
Thus, moles of
Ans, moles of
Now, the mass of water = number of moles x molar mass
Thus, the mass of water
Mass of
Now, mass percent of water is given as:
Thus, the correct answer is 47.
