CHEMISTRY 11 – EXPERIMENTAL UNCERTAINTY OF APPARATUS WORKSHEET. (1) Record the values for the experimental uncertainty encountered in using the following apparatus: Apparatus. Difference between numbered divisions.
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.
uncertainty. Uncertainty is the limit of quan-tifiable measurement with confidence using measuring equipment. One method for determining the uncertainty of an analog measuring device is to utilize the scale provided on the equipment. For example, on a 10-mL graduated cylinder, there are gradu-ations (lines) every 0.1 mL.
d) 10.0 mL: Which is the most practical volume to measure with a 10 mL graduated cylinder? 4) Calculate the % intrinsic error when 0.5 mL of liquid is measured using the following:
Graduated cylinders are designed to contain a range of volumes of a liquid. They are marked with a vertical scale along their length and measure volume by measuring the height of a column of liquid. A tall graduated cylinder with a small diameter is more accurate than a short one with a large diameter.
