Answer:
The correct solution is "3.28 m".
Explanation:
According to the question,
Mol fraction of solvent,
= 0.0558
Molar mass of water,
= 18 g/mol
Mol of H₂O in 1000 g water,
= 55.55 mol
Now,
Let the mol of solute will be "x mol".
Total mol in solution will be "55.55 + x".
As we know,
⇒ The mol fraction of solvent = [tex]\frac{x}{55.55+x}[/tex]
[tex]0.0558=\frac{x}{55.55+x}[/tex]
[tex]x=0.0558[55.55+x][/tex]
[tex]x=3.09969+0.0558x[/tex]
[tex]x-0.0558x=3.09969[/tex]
[tex]x=\frac{3.09969}{0.9442}[/tex]
[tex]=3.38 \ m[/tex]
