Answer: The volume of 0.235 M 
needed to titrate 40.0 mL of 0.0500 M 
is 8.51 ml
Explanation:
To calculate the volume 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:
Thus volume of 0.235 M needed to titrate 40.0 mL of 0.0500 M is 8.51 ml
