Can someone help me with this question

At the end point the addition of 0.1 cm3 of 2 M sodium hydroxide to a solution of 1 M sulfuric acid causes a dramatic change in pH. The table below shows the changes in pH.

volume of sulfuric acid/cm3 volume of sodium hydroxide solution added/cm3 pH of solution
100 99.9

100 100.0 7.0

Calculate the missing pH of the solution shown in the table.

If you've done calculating the pH of buffers by partial neutralisation, this is similar.
Find the initial moles of acid and base, hence the moles of acid remaining after they've reacted. Then find the conc of H+ (bearing in mind sulphuric acid is diprotic) and calculate pH.
