Stoichiometry
CHEMISTRY A
Stoichiometry can be thought of as the math of chemistry. It involves using
relationships between reactants and/or products to determine such quantities as
mass, moles, and number of atoms. Dimensional analysis is a way to simplify
stoichiometric problem solving. In this activity, you will use dimensional analysis in
order to count the number of atoms in a given substance.
1. A sample of gold (Au) has a mass of 35.12 g.
a. Calculate the number of moles of gold (Au) in the sample and record in
Table 1. Show your work.
b. Calculate the number of atoms of gold (Au) in the sample and record
in Table 1. Show your work.
2. A sample of table sugar (sucrose, C12H22O11) has a mass of 1.202 g.
a. Calculate the number of moles of C12H22O11 contained in the sample
and record in Table 1. Show your work.
b. Calculate the moles of each element in C12H22O11 and record in Table
1. Show your work.
c. Calculate the number of atoms of each type in C12H22O11 and record in
Table 1. Show your work.
