If a 0.5 -mL air bubble is persent in the tip of a buret, what error in 10-mL,20 m
l and 40-mL samples will result if the air bubble is dislodged during the dispensing of the sample?

    I presume the question is looking for the percentage error

    so 0.5 x 100%/10 for the 10 ml sample.

    I do however question the size of the air bubble. Most burette tips are about 1 mm diameter and about 1 cm long. So if we have a bubble filling the whole tip the volume is

    0.05 cm x 0.05 cm x 3.142 x 1 cm=

    0.01 cm^3 to 1 sig fig.
