# Session 1: Measurements 📏
In this session, students who can be in class will learn and practice:
- using significant figures as implicit uncertainties, and
- using pipettes, syringes, micropipettes, and burettes for measurements
If you are off-campus, watch the videos on glassware usage. We will be using them again in the coming week.
Significant Figures as Implicit Uncertainty
If you are on-campus, we will work through this together. You do not need to watch the video.
If you are off-campus, watch the first 16:30 of the above video.
Identify the number of significant figures in the following:
555
5505
0.5505
5.505 x 105
5.55 ± 0.005
50
0.50
# Using pipettes, burettes, and syringes
# Volumetric pipettes
# Micropipette
# Burettes
# Homework
Add the Anki deck called Chem Lab Equipment, and learn the names of these chemical equipment. An A3 sheet with drawing is available for you to take notes.
You have previously printed and completed part of the Measurement practice questions. Complete Q1--4 and check your answers. You will be uploading this at the end of the week. This should take no more than 20 minutes.
