CHEM 1011: Chemistry for the Environment

Learn the method to calculate the mass of a substance using its density and volume. This video demonstrates the practical application of density in determining the mass of carbon tetrachloride (CCl4) from a given volume.

This video shows how to determine the number of molecules in a given sample by utilizing the concept of moles, Avogadro's number (6.022 x 10²³), and the molar mass of the substance. It provides step-by-step calculations for different substances, converting mass to the number of molecules and highlighting the versatile application of this approach.

Explore how to calculate the mass and volume of ethylene glycol, a common antifreeze, using its density. Understand the essentials of density-related calculations.
