OL Lab 5: Stoichiometric calculations Identify an unknown compound using
gravimetric analysis
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

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?
