Lecture 8 (9/11/20) Attendance/Comprehension Quiz

In this lecture we will be discussing the mole, molar mass, and writing balanced chemical equations. Let's start our discussion with the mole. The mole is a quantity. Just like the numbers a couple and a dozen, the word mole conveys a number. But instead of 2 or 12, it's a VERY big number: 6.022 x 10²³! Let's start by watching this fun TED Ed video that will help you to understand just how big a mole is. My favorite part... the baby throwing money!
