What is the uncertainty of a 50 mL graduated cylinder?

Recommended Posts

Guest

The graduated cylinder is measured by millimeters, but there is an additional mark that divides each milliliter in half. In other words, between 5 and 10 milliliters, there would be 4 markings. Is the uncertainty recorded to the tenths or the hundredths place?

so, the graduated cylinder is marked every .5ml? 

 The uncertainty is based on the data you collected to some extent. 

  • If your data was: 23.5; 23.7; 23.2 your uncertainty would be +/-.1ml. 
  • If your data was: 23.2; 23.4; 23.6 your uncertainty would be +/- .2ml.
  • If you data was: 23.5; 23.0; 23.5 your uncertainty would be +/- .5ml.

If this was my lab, I would probably use .2ml or .5ml as the uncertainty.
