CHEM 80117: Survey of Chemistry 1

In this analysis, we determine the composition of a solution prepared by dissolving 12.15g of nickel(II) nitrate in 175mL of water (density 1.00 g/mL). The mass percent of nickel(II) nitrate is found to be approximately 6.50%, and the mole fraction of nickel(II) ions in the solution is calculated as 0.00672.

Learn how to determine the number of moles in a given set of atoms using Avogadro's number. This tutorial breaks down the calculation for Aluminum and Iron, simplifying the concept for better understanding.

Learn how to find the density of silver using weight and water displacement. A step-by-step guide to a common laboratory technique.

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 explores the process of fatty acid catabolism, highlighting its occurrence in the mitochondria, the crucial role of mitochondria in energy generation, and the metabolic reactions involved without revealing specific details or conclusions.
