Why is a burette 2 decimal places?

lines, your burette reading should have two digits beyond the decimal point. The number of significant figures indicates how the measurement was made, and if a terminal digit is actually zero, it should be recorded as such. Sample readings from the burette and balance are below.

How many significant figures are in a buret?

4 significant figures
If a person needed only a rough estimate of volume, the beaker volume is satisfactory (2 significant figures), otherwise one should use the graduated cylinder (3 significant figures) or better yet, the buret (4 significant figures).

How many decimal places can a pipette measure?

The precision is printed on the flask for reference. Micropipette are very precise tools for measuring extremely small volumes (less than one milliliter). The number of significant digits you get from a micropipette is printed on the pipette for your reference, but it is usually about 4 significant digits.

How do you read a buret measurement?

Remove any drop hanging from the buret tip by touching the tip to the side of the beaker or wiping the tip with a tissue. Read the initial volume to the hundredths place (0.00 mL). To transfer the liquid, open the stopcock valve until the desired amount of liquid is slowly drained into a container.

What is the precision of a burette?

Burettes are extremely precise: class A burettes are accurate to ±0.05 mL.

How many decimal places are in a thermometer?

With thermometer A you could be sure of the 21 (two digits), but were uncertain about the digit in the first decimal place, so you can quote a reading to three significant figures, as 21.7 °C.

What does a burette look like?

burette, also spelled buret, laboratory apparatus used in quantitative chemical analysis to measure the volume of a liquid or a gas. It consists of a graduated glass tube with a stopcock (turning plug, or spigot) at one end.
