Guest Posted March 11, 2016 Report Share Posted March 11, 2016 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?

IB_taking_over Posted March 11, 2016 Report Share Posted March 11, 2016 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. 1 Reply Link to post Share on other sites More sharing options...
