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 units relationship:
Next, you will explore the relationship between mass, molecular weight, and number of
atoms. This magical equation will enable you to perform derivations of molecular
quantity parameters for various chemical substances. You will feel like Marie Curie
analysing chemical dependencies of chemicals in her French laboratory! Part 1:
Complete the Labster lab: Stoichiometric calculations: Identify an unknown compound
using gravimetric analysis.
Glassware and quantitative transfer
Moving on to the second workbench, you will explore and determine what glassware will
be appropriate for you to use. Your lab guide and mentor, Dr. One, will walk you through
the process of preparing the solution. You will have the freedom to use the equipment
as you like, but only by following Dr. One’s instructions will you be successful in making
the right solution. To make sure you can always redo the essential steps of the process,
