In this course, I'll walk you through the major topics necessary to succeed in general chemistry calculations and lab skills. Each method is covered in detail with background and practice problems for each method. I'll warn you about common stumbling blocks and mental hurdles students normally face, and I'll give you practical problem solving tips and tricks! You're going to do AWESOME!!:) Significant Figures - Significant figures are one of THE easiest ways to stop getting questions wrong. There's nothing worse than missing a question, not because of a mental block, but because of a technicality from significant figures. We'll talk about the major rules for how to apply sig fig rules to mathematical operationsStoichiometry and Balancing Equations - If you can't balance a chemical equation, you've lost the fight before it's even begun. Fortunately, once you get the hang of balancing equations, you'll be one step closer to mastering basic chemistry calculations. Moles - If you're trying to figure out Percent yield and theoretical yield, mastery of the mole is absolutely essential. This is probably THE biggest mental obstacle that students face, which is why I spend 3 separate sections trying to cover the utility and necessity of the mole for chemistry calculationsMolarity - Understanding molarity is key to performing dilutions in Lab. I cover 4 different methods for adjusting the molarity of lab solutions and how to easily perform these adjustmentsTitrations - One of the most common lab calculations that every chemistry student will perform is an acid base titration. I'll cover how to master titrations of a variety of acids as well as how to calculate pKa's using ExcelSpectroscopy and Beer's Law - We'll cover the basic theory behind using spectroscopy to utilize Beer's Law. Calculating the concentration of a lab sample using Beers is one of the most common lab tasks that students struggle with. This section will guide you through how to master these calculations.
