CHEM 3150: Principles of Chemistry I

Uncover the count of chlorine atoms in various chemical compounds. Grasp the calculations in Carbon tetrachloride, Calcium chloride, Phosphorus trichloride, and Sodium chloride. Gain clarity on atomic count across multiple molecules.

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 the process of determining a compound's molecular formula from its empirical formula and molar mass. Understand the calculations and reasoning behind deriving C?H? from the empirical formula CH? with a molar mass of 56.11 g/mol. Gain insight into fundamental chemistry concepts and computations.

Join us in this video as we dive into the intricacies of calculating the net ATP yield from oleic acid (18:1 ??). We'll provide a step-by-step guide and offer helpful hints to ensure an accurate calculation, including a critical step that bypasses acyl-CoA dehydrogenase.

Learn about mass changes in an iron bar when exposed to moist air, including the formation of rust (Fe?O?) and how to calculate the final mass.

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.
