let's compare moles of stuff ok?

Work out the concentration. n=\dfrac{v\times c}{1000}

See that H_2 SO_4 has 2 H in it. So whatever you neutralise it should have 2 lots of OH in it. Or if it only has 1 lot of OH in then the Mol should be doubled.
Pigster ^^ is this right??

Thank you!... I just remembered about diprotic acids. I believe this is right, but will wait until double checked. Would you be able to answer the other chemistry question I have posted? I think I know the answer, but would like to confirm that my reasoning is correct.
