Concentration Made Easy! Molarity, Molality, Percent & Mole Fraction

Описание: Understanding solution concentration is one of the most important skills in chemistry — and in this video, we make it clear and manageable.

We break down the five major ways chemists describe concentration:

✔ Molarity (M) – moles of solute per liter of solution
✔ Molality (m) – moles of solute per kilogram of solvent
✔ Normality (N) – equivalents per liter of solution
✔ Percent Concentration (%) – parts per hundred (mass, volume, or both)
✔ Mole Fraction (χ) – moles of a component divided by total moles

You’ll learn what each unit really means, when to use it, and how to convert between different forms of concentration step by step. We also highlight what extra information you need for conversions, like density, molar mass, and equivalence factors.

By the end of the lesson, you’ll be able to move confidently between concentration units instead of memorizing formulas without understanding.

This video is perfect for:
🔹 High school chemistry students
🔹 Honors & AP Chemistry review
🔹 Homework help and test prep
🔹 Anyone who wants concentration finally explained clearly
