CEM 151: General and Descriptive Chemistry

Learn how to perform dilution calculations for solutions, including copper(II) nitrate, calcium chloride, and lithium carbonate, to achieve specific concentrations.

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.

This video offers insights into the properties and boiling points of different alcohols and ethers, including antifreeze agents like ethylene glycol. We also discuss how molecular structures and interactions impact boiling points, shedding light on key differences among related compounds.

Explore the chemical combination of nitrogen and fluorine to produce nitrogen trifluoride. Learn how to determine the limiting reactant and calculate the theoretical yield using stoichiometry principles.

Learn the step-by-step process to convert moles into grams using the molecular weight of Epsom salts (MgSO?) and carbon dioxide (CO?). From bathtub to soda bottle understand the science behind the amounts
