Question Description
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.
35.12au x (1mol/197g)=.18mol
b. Calculate the number of atoms of gold (Au) in the sample and record in Table 1. Show your work.
.18mol x (6.022 x10^23 atoms/1 mol)= 1.08 x 10^23 atoms.
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.
1.202g (1mol sucrose)/(342g)=3.5 x 10^-3 mol sucrose.
b. Calculate the moles of each element in C12H22O11 and record in Table 1. Show your work.
