The mole fraction of nacl in an aqueous solution is 0.132. how many moles of water are present in 1 mole of this solution?

You could look at it this way.
1 mole of solution = 0.132 of NaCl + x
1 - 0.132 = 0.868 mols of water.

0.868 <<<< answer

The number of moles of water in the solution is 0.868 mole.

Explanation:

The summation of mole fractions of different components in solution is equal 1.0.If a solution composed of different components (a, b, c, d, , n) and each component has its mole fraction (Xa, Xb, Xc, Xd, ,Xn) then Xa + Xb + Xc + Xd + ... + Xn = 1.0For the mentioned NaCl solution; the solution composed of NaCl and water: XNaCl + XH2O = 1.0Also, it is important to define the mole fraction: XNaCl = nNaCl/ntotal and ntotal = nNaCl + nwater; where n id the number of mole (n = mass/molar mass)XNaCl + XH2O = 1.0 and XNaCl = 0.132then Xwater = 1.0 - 0.132 = 0.868

I’m pretty sure it’s false i’m not sure
