It is mathematically possible to convert between different units of concentration: molarity, molality, percent by mass, and mole fraction. The following worked examples show you how to complete these problems. Continue Reading →

The following is a worksheet and answer key designed to walk you through the steps of solution formation and guide you to an understanding of how both intermolecular forces and Continue Reading →

In general chemistry I you learned vocabulary related to solutions, how to read a solubility curve, and how to solve for concentration (molarity, molality, percent by mass/volume). The worksheet below Continue Reading →

Heating/Cooling Curves Explained Calculations with Heating/Cooling Curves How to Read a Phase Diagram

Use the following resources to help you learn about how intermolecular forces contribute to special properties within liquids: Website about properties of liquids: https://www.livescience.com/46972-liquids.html

Intermolecular forces include hydrogen bonds, dipole dipole forces, ion-dipole forces, and London dispersion (van der Waal’s) forces. The following notes can help you learn about each of these forces. Online Continue Reading →

Previously in chemistry class, you learned to draw the Lewis and VSEPR structures of molecular compounds.  Lewis structures provide information about how atoms are connected in molecules, which, in turn, Continue Reading →

Ideal gases follow our assumptions of the kinetic molecular theory.  They always obey PV=nRT, assume molecules have zero volume, and assume no molecular attractions or repulsions.  However, real gases can Continue Reading →
