Aluminum Thickness lab


To find the answers to the aluminum foil thickness lab we must first understand the definition of a mol.  The textbook definition of a mol is the amount of a substance that contains as many atoms, molecules, ions, or other units as the number of atoms in 0.012 Kg of Carbon 12.  It is simply 6.02E23 or Avogadro’s number.  Another thing we must understand is how the aluminum was massed?  We found the mass using molar mass.  The molar mass of aluminum is 26.98 g/mol meaning one mol of aluminum is 26.98.  So to find the # of moles we must use that number.
