CHEM 120 Unit 3 Lab: OL Lab 5: Stoichiometric Calculations: Identify Unknown Compound Using Gravimetric Analysis
Document Content and Description Below
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 m... ass-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 Introduction: Did you know that there are more water molecules in a glass of water than there are sand grains in the Sahara desert? In this simulation you will learn about the relationship between mass, molecular weight and the number of atoms or molecules. You will understand the magnitude and importance of Avogadro’s number. Identify an unknown compound In order to identify a compound where the label has been partly destroyed, you will apply the technique of 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 mass via conversions to moles. Stoichiometric calculations with moles You will perform a realistic gravimetric analysis with detailed instructions on what to do and why to do it in every step of the experiment. From balancing the equation to recognizing the stoichiometry of the reactants and finding out which equation to employ in the calculations you will identify of an unidentified compound. What compound is it? At the end of the simulation, you will have finalized all of the stoichiometric calculations and the answer to the question should be clear… Can you see what compound it is? Part 1: Complete the Labster lab: Stoichiometric calculations: Identify an unknown compound u [Show More]
