How many planet earth's are needed to have a mole of people?
Mole 6.02 x 10^23
Planet Earth 6 x 10^9
X x 6 x 10^9 = 6.02 x 10^23
               X = 6.02 x 10^23/ 6 x 10^9
               X = 1 x 10^14
               X = 100,000,000,000,000

Na Sodium intake for the day?
1500 mg = 1.5 g
23 g Na Atoms/ 1 mole of Na Atoms
0.06 mole Na Atoms x 6.02 x 10^23 Na Atoms/1 mole Na Atoms = 6.02 x 10^23/10 = 6.02 x 10^22
