CHEM 11862: Organic Chemistry

This video outlines the process of calculating the number of moles in various elemental samples. It begins by explaining the relationship between molar mass and atomic weight. Each sample's mass is divided by the respective element's molar mass to find the number of moles. It provides detailed calculations for four elemental samples: zinc (Zn), argon (Ar), tantalum (Ta), and lithium (Li), converting results to scientific notation where necessary. The script demonstrates how to determine the mole

We explore the impact of increasing the concentration of ethylene glycol in an antifreeze mixture, explaining the resulting effect on the freezing point of the solution by examining its interaction with water molecules.

In this video, we classify substances as elements, compounds, or mixtures, with air and soy sauce as mixtures, iron as an element, and table salt as a compound.
