Someone help please let me know what the answer is

Answer:
7.25 mol
Explanation:
Given data:
Number of moles of sodium carbonate formed = ?
Number of moles of carbonic acid = 7.25 mol
Solution:
Chemical equation:
H₂CO₃ + 2NaOH → Na₂CO₃ + 2H₂O
Now we will compare the moles of sodium carbonate with carbonic acid.
H₂CO₃ : Na₂CO₃
1 : 1
7.25 : 7.25
So from 7.25 moles of carbonic acid same number of moles of sodium carbonate will form.
