Suppose a 1.0-mL air bubble is trapped in the tip of your buret and you don't notice it before measuring out liquid samples with the buret. What percentage error would be introduced in a 35.0 mL sample of liquid if the air bubble comes out of the tip of the buret while the liquid sample is being transferred?
