Answer : The molar concentration of is,
Explanation : Given,
Equilibrium constant =
Concentration of = 0.050 M
The balanced equilibrium reaction is,
The expression of equilibrium constant for the reaction will be:
Now put all the values in this expression, we get :
Therefore, the molar concentration of is,
