A unit is the frequently arbitrary designation we have given to something to convey a definite magnitude of a physical quantity and every quantity can be expressed in terms of the seven base units that are contained in the international system of units. Hank thinks this is a thrilling subject, and while you may not agree, it is a subject that is very important if you want to be a scientist and communicate with accuracy and precision with other scientists. So listen up and learn something or Hank might have to kill you! (NOT REALLY!)

Ahhhh!!!! Sig figs!!!!! They’re one of the most hated and pesky chemistry topics, but they’re used so frequently it’s super important to learn their rules.
In this video, I go over all the sig fig rules that you need to know for your chemistry/ science class. Significant figures are important because in science, scientists use sig figs to communicate with each other about how accurately they actually know the information they’re showing you.

Understanding Significant Figures (also known as “sig figs”) is incredibly important in Science! When you collect data, whether you’re doing Chemistry, Biology, Physics, or Engineering, you need to notice how precise your tools allow you to be. There should be one estimated digit in your data.
This is where the idea of significant figures comes from - from measurement! Make a note of how precise your data is before you start calculating. Then you round off to the correct number of significant digits at the end of your calculations. Otherwise, you give people the wrong idea of how precise your initial measurements were.
In this video, we’ll go over all the rules for determining significant figures. We also do examples of sig figs in calculations! We show you the rules for adding, subtracting, multiplying, and dividing. We even cover the advanced topics of significant figures in logarithms and when you raise 10 to a power.

About our instructor:
Kimberly Hatch Harrison received degrees in Biology and English Literature from Caltech before working in pharmaceuticals research, developing drugs for autoimmune disorders. She then continued her studies in Molecular Biology (focusing on Immunology and Neurobiology) at Princeton University, where she began teaching as a graduate student. Her success in teaching convinced her to leave the glamorous world of biology research and turn to teaching full-time. Kimberly taught AP Biology and Chemistry at an exclusive prep school for eight years. She is now the head writer and producer of Socratica Studios.

How many atoms in 5.5 moles? How many moles is 4.6 x 10^24 sulfur atoms? We'll solve problems like these, where we convert back and forth between moles and the number of atoms or molecules that we have. We'll be using both a common sense approach, and also a standard conversion factor method. We'll learn how to use a scientific calculation to do this math, and we'll see how to round our answers with scientific notation and significant figures.

In this video, I define Precision and Accuracy and use examples to illustrate the differences between them. I discuss the process of using a ruler to measure length and how to add an estimated digit to the end of a measurement. Finally, I explain the rules for determining the number of significant figures in a measurement.
