How to Calculate the Average Atomic Mass - 3 EASY STEPS

The video tutorial explains the concept of atomic mass, differentiating between mass number and average atomic mass. It introduces isotopes and their role in determining atomic mass, emphasizing the importance of percent abundance. The tutorial provides a step-by-step guide to calculating average atomic mass using examples of potassium and gallium isotopes. It highlights the significance of rounding in periodic tables and introduces atomic mass units (AMU).

What are the three isotopes of potassium mentioned in the video?

Describe the steps involved in converting percent abundance to decimals.

Why might the average atomic mass calculated differ from the value on the periodic table?
