CHEM 120 Week 3 Virtual Lab; Part I, Part II, Part III
OL Lab 3: Stoichiometry: Avogadro’s number and molecular calculations / Solution Preparation: From salt to solution Learning Objectives: Explain the relationship between mass, molecular weight, and numbers of atoms or molecules and perform calculations deriving these quantities from one another Perform mass-to-mass stoichiometric calculations via conversions to moles Identify the limiting and excess reagents in a chemical reaction Calculate the theoretical, actual and percent reaction yield Define Avogadro’s number and describe the mole quantification of matter Explain relationship between mass, molecular weight, and numbers of atoms or molecules Perform conversion and derivations calculations using key molecular quantity parameters Define Avogadro’s number and describe the mole quantification of matter How many moles of sand grains has the Sahara desert? What is the only equation you ´ll ever need in chemistry? The short stoichiometry simulation will help you answer those questions! Follow the footsteps of great chemists and learn about key molecular parameters based on one and only star of chemistry calculations: Avogadro’s Law! Concept mole and Avogadro’s Law: Your first mission in this short simulation is to familiarize yourself with the concept of mole and the way of counting molecules of substances using the one and only Avogadro’s Law. You will learn how to convert huge numbers of particles into handy Avogadro’s number, extensively used by all chemists around the world! Chemical uni
