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

✓

Answer

Correct option: A.

$\frac{{{\rm{No}}\,{\rm{. of \,moles\, of\, solute}}}}{{{\rm{Volume\, of \,solution\, in\, litre}}}}$

a
Molarity $(M)$ is defined as the number of moles of solute per liter of solution.

$\text { molarity }=\frac{\text { moles of solute }}{\text { volume of solution in litre. }}$
