Given :-
To Find :-
Solution :-
As we know that ,
[tex]\longrightarrow Molarity (M )=\dfrac{Number\ of \ moles \ of \ solute }{Volume\ of \ solution\ (in \ L) } [/tex]
Substitute ,
[tex]\longrightarrow M =\dfrac{10}{500L}[/tex]
Simplify,
[tex]\longrightarrow M = \dfrac{1}{50} [/tex]
Convert into decimal ,
[tex]\longrightarrow \underline{\underline{ M = 0.02 \ mol \ L^{-1}}} [/tex]
This is the required answer .
