1. The Mole Discovery Purpose: to discover the mole
Hypothesis: If the mass is determined, then the number of moles and atoms can be determined
Procedure: Weigh the bags of elements and determine the number of moles and atoms

2. Data Table: (not all have A,B,C)
Element A B C
mass in grams
Al ___ ___ ___
C ___ ___ ___
Ca ___ ___ ___
Cu,Pb,S,Si,Sn,Zn

3. Results Table Element: A B C Calculate mass moles atoms for ABC Al C
Cu,Pb,S,Si,Sn,Zn

4. Conclusion Restate Purpose: to discover the mole
Procedure: Weigh the bags of elements and determine the number of moles and atoms
State the relationships between the mole, avogadro’s number and atomic mass
