<u>Answer:</u> The concentration of comes out to be 0.843 M.
<u>Explanation:</u>
To calculate the concentration of acid, we use the equation given by neutralization reaction
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is
We are given:
Putting values in above equation, we get:
Hence, the concentration of comes out to be 0.843 M.
