Listen "Topic: Empirical Formula"
Episode Synopsis
This episode explains how to find a compound's empirical formula—the simplest whole-number ratio of its elements. It presents a four-step method: (1) convert mass or mass percent to moles, (2) divide all mole values by the smallest number, (3) convert the resulting ratios to whole numbers, and (4) write the formula. The episode demonstrates how this process works for both simple and hydrated compounds and explain how to use the empirical formula to determine the molecular formula if the molar mass is known.
