Answer : The concentration of
ion is

Explanation :
First we have to calculate the moles of
.

The balanced chemical reaction will be:

From the reaction we conclude that,
1 mole of
dissociate to give 3 moles of
ion and 1 mole of
ion
So,
0.03 mole of
dissociate to give
moles of
ion and 0.03 mole of
ion
Now we have to calculate the concentration of
ion.


Therefore, the concentration of
ion is
