Figure 01: Different types of glassware for measuring liquid volume. How to use a graduated cylinder? 1. Look straight across at the graduated cylinder to avoid parallax error (Figure02). Read the bottom of the meniscus (the curved surface of the solution).2. Important note about significant digits: A 100 mL graduated cylinder hasmarks at 1-mL intervals; therefore, you should estimate the volume to thenearest 0.1 mL. This is done by dividing the space between the 1-mL marksinto ten imaginary spaces and deciding which of those spaces the meniscusis closest to. It’s OK if you aren’t sure—use your best judgment. The last digitof any measurement is supposed to be uncertain or an estimate or bestguessed number.3. If the meniscus is exactly on a line, you still record the volume to the nearest0.1 mL. For example, if it’s right on the 27-mL line, record the volume as“27.0 mL” to show that you read it carefully and the margin of error is 0.1mL. Remember, trailing zeros after the decimal point…
