It is important to make certain that there is no air bubble in the tip of the buret below the stopcock before the initial reading of the liquid level in t he buret is taken. If a 0.5-mL air bubble is present in the tip of a buret what percentage error in 10-mL 20-mL and 40-mL samples will result if the air bubble is disloged during the dispensing of samples?

Not simple chemistry but simple logic.
You think you delivered, say, 10 mL from burette readings. But in fact 0.5 mL of that has gone to fill the space taken up by the air bubble. So what did you deliver and what was the percentage error?
