Answer: Molarity of
is 1.2 M.
Step-by-step 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 molarity of
is 1.2 M if 250 mL of the acid was used to neutralize 200 mL of 1.5 M solution of
