What is the mole fraction of the solute in a 1.00 m aqueous solution?
  1. A
    1.770
  2. B
    0.0354
  3. C
    0.0177
  4. D

Correct answer: C

Number of moles of water in 1000 g = 100018{{1000} \over {18}}181000​ = 55.56 mol

Thus, mole fraction of solute = 11+55.56{1 \over {1 + 55.56}}1+55.561​ = 0.0177
