IB Chemistry: The Mole Concept & Unit Conversions

Build the foundation for all IB Chemistry calculations.

Many IB Chemistry students struggle not because the concepts are impossible, but because they were never taught the fundamentals in a clear and structured way. This course is designed to fix that.

In this course, you will develop a deep understanding of the core skills that everything in IB Chemistry builds on. You will start with essential concepts such as accuracy vs precision, systematic and random errors, and percentage error—so you truly understand how experimental results are evaluated.

You will then master significant figures and scientific notation, learning how to correctly report answers with confidence. From there, the course moves into the most important calculation skills in chemistry, including unit conversions, dimensional analysis, the mole concept, and molar mass.

You will also learn how to work with gas volume and density, allowing you to confidently move between mass, moles, particles, and volume—skills that are essential for success in stoichiometry and more advanced IB topics.

This course is not just about memorizing formulas. It is designed to help you think through problems step-by-step, avoid common mistakes, and build real confidence in your calculations.

There are no prerequisites for this course. It is designed to be simple, clear, and accessible, even if you are just starting IB Chemistry or need to rebuild your foundation from the beginning.

By the end of this course, you will have a strong foundation in quantitative chemistry and be fully prepared to tackle topics like stoichiometry, limiting reagents, gases, and concentration.

Whether you are struggling to keep up or aiming for a top score, this course will give you the clarity and skills you need to succeed in IB Chemistry.
