What would be the effect on the percent acetic acid if 30 mL of vinegar had been used in place of 50 mL? Explain?

You are asking a question about an experiment you performed but I'm not privy to your set of instructions, I have no clear idea of what you did, nor any other details. I will hazard a guess that you titrated 50 mL of vinegar. I'm guessing you titrated it with either NaOH or KOH (probably NaOH) and you determined the percent acetic acid in the vinegar. If I've guessed right, then titrating a 30 mL sample of vinegar instead 50 mL of vinegar will have no effect on the answer you get ALTHOUGH the accuracy of the larger sample MAY be slightly better unless the 50 mL sample required you to use more than one buret full of the NaOH in which case the 30 mL sample is likely to give better accuracy. My best guess is that your prof wants there will be no difference. If I had numbers you had used I could give a better answer but I'm really flying blind with this. I hope this is not too confusing but I've tried to cover all bases.
