17 cze 2023 · If you look at a 10 mL graduated cylinder, for example, the smallest graduation is tenth of a milliliter (0.1 mL). That means when you read the volume, you can estimate to the hundredths place (0.01 mL). You must use the bottom of the meniscus to determine the volume in the 10 mL graduated cylinder.

The table given below lists the absolute uncertainties for some equipment used in the Chemistry lab. The absolute uncertainty expresses the margin of uncertainty associated with a reading, a measurement, or a calculation involving several readings.
Figure \(\PageIndex{1}\): To measure the volume of liquid in this graduated cylinder, you must mentally subdivide the distance between the 21 and 22 mL marks into tenths of a milliliter, and then make a reading (estimate) at the bottom of the meniscus.
If you look at a 10-mL graduated cylinder, for example, the smallest graduation is a tenth of a milliliter (0.1 mL). That means when you read the volume, you can estimate to the hundredths place (0.01 mL). The bottom of the meniscus is used to determine the volume in a 10-mL graduated cylinder (Figure 1). Figure 1.
