The extent to which a solute dissolves in a solution is expressed by the solution’s concentration. The Molarity Formula Concentration is most often expressed as molarity (M). Molarity (M) = moles of solute (mol) / liters of solution (L) -or- The best way to understand how to use the molarity formula is to practice…

We’ll do some empirical formula calculations and problems in just a second, but first let’s get some definitions out of the way. Empirical Formula Empirical Formula = the simplest whole-number ratio of atoms in a compound. Molecular Formula Molecular Formula = the exact formula of a…

What the heck are “ isotopes?” What’s the definition of an isotope? How are they different? These are all answers that we’re going to answer here today. But first, we must introduce the atom and its components by quickly discussing Modern Atomic Structure… A Brief Introduction to Modern Atomic Structure …

There are 3 FACTORS that must be considered when determining the solubility of a solution. They are: 1. Structure Effects 2. Pressure Effects 3. Temperature Let’s take a look at each of these factors in detail. 1. Structure Effects ➞ Structure Effects = “like dissolves like” Solubility…

Intermolecular forces occur between molecules. Intramolecular forces (bonds) occur within molecules. Types of Intermolecular Forces There are two types of intermolecular forces: 1. Dipole-Dipole Forces = only occur between polar molecules. ➞ Note: Hydrogen Bonds are a special type, or “subset” of Dipole-Dipole Forces. 2. London Dispersion Forces =…
