For instance, just because water is made up of one oxygen atom and two hydrogen atoms, that doesn't mean you can say water is 33% oxygen and 67% hydrogen. To determine percent composition by mass, you need to refer to a Periodic Table so you can see what each kind of atom weighs. With a little math, you'll be able to see that water is 88.81% oxygen by mass, and 11.19% hydrogen by mass. In this video, we work through two examples in full. ⬣⬣⬣ LESSON CHAPTERS: 0:00 Introduction 0:40 Definition of percent composition 1:11 Example 1: What is the percent composition of water - H2O 3:25 Example 2: What is the percent composition of glucose - C6H12O6 Do you need to understand Empirical Formulas? https://www.socratica.com/lesson/empi...

She 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, accepting a position at an exclusive prep school, where she taught biology and chemistry for eight years.
