The mole friction of the solute in one molal aqueous solution is:

Options

  1. A0.009
  2. B0.018
  3. C0.027
  4. D0.036

Correct answer

B. 0.018

Step-by-step solution

1 mole of solute present in 1 ~kg of H ₂ O 1 mole of solute present in 1000 18 ~g . mole of H ₂ O aligned X _ solute & = 1 1000 18 +1 = 18 1018 & =0.01768 0.018 . aligned Related Theory The molar fraction can be represented by X . If the solution consists of components A and B , then the mole fraction is, Mole fraction of solute = Moles of Solute Moles of Solute + Moles of Solven = n_A n_A+n_B Mole fraction of solute = n_B n_A+n_B Therefore, the sum of mole fraction of all the components is always equal to one.
