Answer: The molar concentration of sulfuric acid in the original sample is 1.943 M
Step-by-step explanation:
To calculate the molarity 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 NaOH.
We are given:

Putting values in above equation, we get:


Now to calculate the molarity of original solution:


Thus the molar concentration of sulfuric acid in the original sample is 1.943 M
