OL Lab 5: Stoichiometric calculations Identify an unknown compound usinggravimetric analysisLearning Objectives:Explain the relationship between mass, molecular weight, and numbers of atoms or moleculesand perform calculations deriving these quantities from one anotherPerform mass-to-mass stoichiometric calculationsviaconversions to molesIdentify the limiting and excess reagents in a chemical reactionCalculate the theoretical, actual and percent reaction yieldDefine Avogadro’s number and describe the mole quantification of matterIntroduction:Did you know that there are more water molecules in a glass of water than there are sand grains in theSahara desert? In this simulation you will learn about the relationship between mass, molecular weightand the number of atoms or molecules. You will understand the magnitude and importance ofAvogadro’s number.Identify an unknown compoundIn order to identify a compound where the label has been partly destroyed, you will apply the techniqueof gravimetric analysis. To do so, you must first learn to understand the relationship between mass,moles and molecular weights and how to perform stoichiometric calculations from mass to massviaconversions to moles.
