How many decimal places should be used to record the volume of a 10 ml volumetric flask?

Traditionally, 2 decimal places should be used to record the volume of a 10 ml volumetric flask. Recording the volume 2 decimal places means that you are measuring, or rounding your measurement, to the hundredth decimal place, whereas if you were measuring just 1 decimal place, you'd be measuring the tenth decimal place. When we say 2 decimal places, we mean that there should be two numbers that come after the decimal point, regardless of whether or not there is a number that is standing in front (or visually, to the left) of the decimal point.

What is a volumetric flask and its uses?
A volumetric flask is a piece of laboratory glassware used in analytical chemistry for the preparation of solutions. It is made of glass or plastic and consists of a flat bottomed bulb with a long neck, usually fitted with a stopper. The stopper is normally made in a chemically resistant plastic such as polypropylene rather than glass. The neck has a single ring graduation mark and a label. The label should show the nominal volume, tolerance, calibration temperature, class, relevant manufacturing standard and the manufacturer’s logo. The glass or plastic is generally clear but may be amber colored for handling light sensitive compounds such as silver nitrate or vitamin A.
When using a pipet can you state the volume of the aliquot without calculating it?
Yes, cause an aliquot is a small volume of something and I believe in this experiment you are also using a volumetric pipet, which should give you the exact volume of the aliquot.
Why is it necessary to calibrate a thermometer and volumetric?
In order to get a more precise and accurate reading.
How many significant figures should be reported for the difference between 18.6172 mL and 18.57 mL?
Only 3 significant figures, after rounding.
Differentiate significant figures and non-significant figures?
Significant figures are those that are actually required to specify a quantity, and can be used in working with that quantity. Thus if you are using a ruler with millimeter divisions to measure something, you can only measure to the nearest millimeter. If you were measuring the diameter of a circle in order to calculate the perimeter of the circle, you could look up the value of Pi to as many decimal places as you like, say 10 places, and so your value of the perimeter ( Pi x d) would appear to be extremely accurate having a value quoted to 10 decimal places. But in fact it would only be accurate to the nearest millimeter, as was the diameter you measured, so the decimal places beyond the number of whole millimeters should be discarded, as non-significant. They could be real, but you can't say if they are or not, so best not to quote them. This is an example of the idea-don't present a result as more accurate than the components which went into it.
How many decimal places should be used to record the volume of a 250ml volumetric flask?
The answer depends on the graduation on the flask.
How many decimal places should be used to record the volume of a 250 ml volumetric flask?
Normally one decimal place is appropriate.
If the measure of a length is in centimeters and is to be converted to hectometer by how many decimal places should the decimal point be moved?
It should be moved 4 places.
Jhon is multiplying two factors each with one decimal place he says that the product should also haveonly one decimal place explain?
The number of decimal places in the product must equal the total number of decimal places in the factors. John's product should have 2 decimal places.
Should 3 decimal places or 1 decimal places which is bigger?
The number of decimal places has no bearing on the relative value. 0.2 is greater than 0.137 0.402 is greater than 0.3

How many digits should the sum have after the decimal point?
The answer depends on how many decimal places are in the summands.

How are decimal and percent the same?
Move the decimal 2 places to right to change any decimal to a percent. Reverse, move decimal 2 places to the right to change any percent to a decimal. Knowing this should show that they represent the same quantities.
