Lab Question (Based on your aluminum foil sample) If the population of the world is 5.6 x 10^9 individuals, how many aluminum atoms could you distribute to each person from your sample of aluminum foil?

You have to start with the mass of your aluminum foil so weigh it out, let's call it m.
Then find the molecular weight in g/mol from the periodic table, we'll call this MW.
Next, calculate how many mols of Al are in your foil:
# mols = m / MW
Then calculate the number of atoms using Avogadro's Number.
# atoms = # mols * Avogadro's Number
Finally, divide the # atoms by the population of the world to see how many atoms each person could get from your sample.

Do a very accurate massing of your sample.
Convert this value to 'moles' (refer to the atomic weight value)
Convert the mole value to atoms. (standard conversion, 6.022 x 10^23)
Divide the # of atoms value by the population.
