The final concentration is 0.226 M.
Explanation:
In this problem the dilution has occurred two times. So the symbol initial concentration, concentration after first dilution and the concentration after second dilution is given as C1, C2, and C3 respectively. Same can be done for the volume i.e, V1, V2, and V3 will be the initial volume, the volume taken after first dilution, and the volume after second dilution.
So, let's use the dilution formula for the first dilution
Now, for the second dilution
