Answer:

Explanation:
Hello,
In this case, as the reaction between sodium hydroxide and sulfuric is:

We can notice a 2:1 molar ratio between the base and the acid, for that reason for the titration at the equivalence point we find:

Which in terms of concentrations and volumes is:

In such a way, solving for the required volume of base we find:

Best regards.
The covalent Lewis structure is that I hope this help
The wrong one is

It is crucial to match your units of Pressure, Volume, number of mole, and Temperature with the units of R. If you use the first value of R, which is 0.082057 L atm mol-1K-1, your unit for pressure must be atm, for volume must be liter, for temperature must be Kelvin.
