Atomic mass is the mass of a specific isotope. It is the total mass of protons, neutrons, and electrons in a single atom (when the atom is motionless). It is the mass of 1 mole of atoms.
The following measurements are simply words that stand for numbers/increments.
A “dozen” is a measurement increment of 12. (One dozen eggs = 12 eggs)
A case is a standard increment of measurement for a particular thing. (One case of soda = 24)
A gross is a quantity equal to a dozen dozen, or 144.
A mole is the amount of substance with as many atoms or other units as there are 12 grams of carbon isotope C-12. The number of atoms in a mole is called Acogardo’s number, the value of which is approximately 6.022 x 1023 mol-1. One mole of a substance always contains almost exactly the relative atomic mass of that substance, expressed in grams.
How many planet earths are needed to have a mole of people?
Assuming there are 6,000,000,000 people on this planet. (6 x 109)…
1 mole = 6.022 x 1023
Y x 6 x 109 = 6.02 x 1023
Y = 1.003 x 1014
Y = 100,000,000,000,000
