What is the circumference of a water droplet from a pipette?
58.36492
Why pipette is more accurate when determine the density of water?
because electronic pipette has the accuracy 0.01 microliter than burette.
What would be the precaution for drop left in pipette?
For the majority of pipettes the last drop should be left in the pipette; read the recommendation from the pipettes catalog.
What is the function of a water aspirator?
A rubber aspirator sucks up liquid into the pipette.
What is a pipette made out of?
a pipette is made out of pyrex or plastic.
How is a pipette prepared?
1. Clean the pipette with a solution of an adequate reactive. 2. Wash with tap water. 3. Wash with demineralized water. 4. Dry the pipette.

You are using a pipette that has a mark every 0.1 mL. If you want to measure 5.15 mL of liquid using this pipette to what level should you fill the pipette?
The bottom of the meniscus should be halfway between the 5.1-mL mark and the 5.2-mL mark
Why should you not blow out the small amount of solution that remains in pipette when measuring liquids?
The calibration of a pipette is made taking into account this small volume.

What is a Mohr Pipette used for in chemistry?
A Mohr pipette is a type of pipette that measures the volume of dispensed liquids. It is less accurate compared to a volumetric pipette.
Why should a bulb be used on a pipette rather then your mouth when you are measuring a liquid?
I donno
What safety item should be used with pipette?
do not tilt the micropipette, otherwise the solution will go inside of it and it is difficult to take out
