CHEM 204: Organic Chemistry I

This instructional video guides you through the process of determining the number of molecules in a given sample. It illustrates the conversion from grams to moles using the molar mass of the substance and then to molecules using Avogadro's number, providing a practical example with ethane (C?H?) to calculate approximately 6.67 x 10²¹ molecules in a 0.334 g sample.

Discover how to precisely calculate mass, moles, formula units, and atoms in various compounds. Understand the concept with examples like chromium(III) sulfate decahydrate, dichlorine heptoxide, and lithium sulfate. Master chemistry calculations through a step-by-step guide.

Dive into the accuracy of four chemical reactions involving compounds like Barium Nitrate and Lithium Chloride. Discover which reactions yield precipitates which are correct and which need correction. A comprehensive review from Barium Sulfate formation to Lead Chloride precipitation

In this tutorial, we break down the principle of density, illustrating it as a measure of mass per unit volume. Using an osmium cube as a practical example, we walk viewers through the steps of computing its density, demonstrating the interplay between mass, volume, and particle arrangement.
