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

Answer 1

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.

Answer 2

This will depend upon the individual Burette used - some measure to one mL and therefore would need a single decimal point while others measure to one tenth of a mL. When in doubt, you should check the gradation of the instrument and then add one decimal point to that gradation.

Answer 3

Typically, the volume of a 10 ml volumetric flask is recorded to two decimal places (e.g., 10.00 ml). This level of precision is sufficient for most common laboratory measurements.
