Answer : The volume of 
required to neutralize is, 340 mL
Explanation :
To calculate the volume of base (NaOH), 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 NaOH.
We are given:
Putting values in above equation, we get:
Hence, the volume of required to neutralize is, 340 mL
Relative dating can only determine the sequential order<span> of events, not the exact date which something occurred. It is useful for being able to determine a timeline of events in an exact point, but won't give a full picture of events in the past nor account for the age of material.
