Answer:
0.0445 M is the initial concentration of sulfurous acid.
Explanation:

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 NaOH.
We are given:

Putting values in above equation, we get:


0.0445 M is the initial concentration of sulfurous acid.
