Easy Acid-Base titration problem i think

Easy Acid-Base titration problem... i think URGENT!

So i just got my final exam for chem 2 back and i missed an A by two question. The thing is these two questions i was for sure i got right but apparently i didnt... here they are:

Use the following information: 50 mL solution of 0.053M HCL is titrated with .080M KOH
(I assumed a strong acid strong base titration)

First question:
How many ml KOH are needed to reach the equivalence point?
I put 33.1 mL which was wrong

Second question:
What would be the pH at the equivalence point?
I put 7 which was wrong

Any help?

No help, I get the same answers. Odd.

33.1mL looks OK, final pH of 7 looks OK as well.

I can see a reason why final pH should be 6.98 or 6.99, but I doubt you were expected to dig that deep.

Third to attest the correctness of your answers. You deserve an A, so something's up.
