Answer 1

Answer: Moles of water are 0.868

Step-by-step explanation:

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

moles fraction=
`\frac{\text {number of moles of solute}}{\text {number of moles of solution}}`

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.
