1.5 Uncertainty in Measurements
Measurements can have degrees of uncertainty. In this video we talk about what that means, and how our measuring devices can affect how precise our data is. Assignment: 1. In analyzing a sample of polluted water. a chemist measured out a 25.00 - mL water sample with a pipet. At another point in the analysis, the chemist used a graduated cylinder to measure 25 mL of a solution. What is the difference between the measurements 25.00 - mL and 25 - mL?
