Welcome to the fascinating world of chemistry, where it all starts with... the mole! This video is a comprehensive and accessible introduction to one of the key concepts in the science of matter – the mole, Avogadro's number, and molar mass.

Why is the mole so important? How can we understand this mysterious number that connects the world of atoms and molecules with what we see every day? The video explains step-by-step how the conversion between the mass of a substance and the number of its molecules works. You'll understand why chemists use the concept of the mole, how to "weigh" it, and why Avogadro's number is needed.

The video contains a set of ten carefully selected problems, solved in real time, with detailed explanations of each step. The problems are arranged from simple to complex, so that everyone – regardless of their level – can get the most out of this material. It's an ideal resource for high school students, college students just starting their chemistry journey, and anyone curious about the microscopic world of molecules.
