Total Moles Explained: Understanding How Molar Calculations Work When working with chemical reactions, quantifying the amount of substance often requires precise molar calculations. Understanding how to add moles is fundamental for accurate stoichiometry, lab work, and chemical analysis. In this article, we explore a straightforward example: Total moles = 0.18 moles + 0.07 moles = <<0.18 + 0.07 = 0.25>>0.25 moles. We break down the process, clarify units, and emphasize why proper molar addition is vital in chemistry. --- ### What Are Moles and Why Do They Matter?
