Answer:

The final water level in the burette is
23.4\ cm^3

Explanation:

It is given the water level in a burette is
30\ cm^3. The burette loses 55 drops, each one with an average volume of
0.12\ cm^3.

If each drop has a volume of
0.12 cm^3, then 55 drops have a volume of
55*0.12\ cm^3=6.6\ cm^3

The new level of water in the burette is the subtraction of the original contents minus the volume loss.

New volume =
30\ cm^3-6.6\ cm^3

New volume =
23.4\ cm^3

The final water level in the burette is 23.4\ cm^3
