MCQ

Mole fraction $(X)$ of any solution is equal to

A
$\frac{{{\rm{No}}\,{\rm{. of\, moles\, of\, solute}}}}{{{\rm{Volume\,of\, solution\, in\, litre}}}}$
B
$\frac{{{\rm{No}}{\rm{. \,of\, gram\, equivalent \,of\,solute}}}}{{{\rm{Volume\,of\, solution\, in\, litre}}}}$
C
$\frac{{{\rm{No}}{\rm{.\, of\, moles \,of\, solute}}}}{{{\rm{Mass\,of \,solvent\, in\, kg}}}}$
✓
$\frac{{{\rm{No}}{\rm{.\, \,of\, moles\, of\, any\, constituent}}}}{{{\rm{Total\, no}}{\rm{. of\,moles \,of \,all\, constituents}}}}$

✓

Answer

Correct option: D.

$\frac{{{\rm{No}}{\rm{.\, \,of\, moles\, of\, any\, constituent}}}}{{{\rm{Total\, no}}{\rm{. of\,moles \,of \,all\, constituents}}}}$

d
Mole fraction is defined as the number of molecules of a constituent divided by the total number of all molecules i.e.,

$=\frac{\text { No. of moles of any constituent }}{\text { Total no. of moles of all constituents }}$
