Reacting Masses and Stoichiometric Calculations

Introduction: Why masses in chemistry are not random 🎯

Hello students, in chemistry, substances react in fixed patterns. A chemical equation is not just a sentence about what changes; it is a mathematical map of how particles combine and rearrange. This lesson explains how to use balanced equations, mole ratios, and molar mass to predict reacting masses and product amounts. These skills are essential in IB Chemistry SL because they connect the particulate nature of matter to real laboratory measurements like grams, volumes, and concentrations.

By the end of this lesson, you should be able to:

• explain key terms such as $$mole? Actually need valid latex. Fix carefully.
