Question

The mole fraction of the solute molal aqueous solution is:

विकल्प

• 0.09

• 0.018

• 0.027

• 0.036

Answer 1

0.018

Explanation:

Mole fraction `=n_"(solute)"/(n_"(solute)"+   n_"(solvent)")` 

Here, n_(solute) = 1 mol

`n_"(solvent)" = 1000/18 = 55.55` mol

∴ Mole fraction `= 1/(1+ 55.55) = 1/56.55 = 0.018`
