Presentation transcript:

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

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

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

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
