Answer:
The final water level in the burette is [tex]23.4\ cm^3[/tex]
Step-by-step explanation:
It is given the water level in a burette is [tex]30\ cm^3[/tex]. The burette loses 55 drops, each one with an average volume of [tex]0.12\ cm^3[/tex].
If each drop has a volume of [tex]0.12 cm^3[/tex], then 55 drops have a volume of [tex]55*0.12\ cm^3=6.6\ cm^3[/tex]
The new level of water in the burette is the subtraction of the original contents minus the volume loss.
New volume = [tex]30\ cm^3-6.6\ cm^3[/tex]
New volume = [tex]23.4\ cm^3[/tex]
The final water level in the burette is 23.4\ cm^3
