Answer: New concentration of 
is 0.23 M.
Explanation:
The given data is as follows.
Moles of = 0.06 mol
Moles of 
= 0.08 mol
Therefore, moles of 
added are as follows.
Moles of = 
= 0.003125 mol
Now, new moles of = 0.06 + 0.003125
= 0.063125
Therefore, new concentration of will be calculated as follows.
Concentration = 
= 0.23 M
Thus, we can conclude that new concentration of is 0.23 M.
