In this animated chemistry lecture we will learn how to logically understand the concept of mole and mole calculations. We will learn this concept in two steps. First we will learn the theoretical understanding of the concept of mole. Later we will apply these theoretical understanding to perform three numerical problems related to mole. These three numerical problems will help us understand every aspect of mole. Following are the statements of these numerical problems:

(a). Calculate number of CO2 molecules in 48g of CO2 gas.

(b). 1.50 x 10^(24) molecules of an unknown compound weigh 85g. What is the molar mass of that unknown compound?

(c). Hydrogen gas is burnt in the presence of oxygen to produce water. If you have 12g of hydrogen gas, how much oxygen gas will be required to completely burn the given hydrogen gas?

This animated chemistry lecture is fifteenth one in this series of "Basics of Chemistry". I will try to make more animated lectures like this in this series.

I hope you will like this lecture. If there is any feedback related to the lecture or animation, you can give that in comments.

You can download these slides from the following Google Drive folder.
