Answer: Moles of water are 0.868

Explanation:

Mole fraction is the ratio of number of moles of one component to the total number of moles present.

moles fraction= [tex]\frac{\text {number of moles of solute}}{\text {number of moles of solution}}[/tex]

Given : mole fraction of NaCl = 0.132

Thus 0.132 moles of NaCl are present in 1 mole of solution

moles of water = moles of solution - moles of solute

moles of water = (1 - 0.132) = 0.868

Thus moles of water are 0.868.
