Astronomers estimate that there is a mole (6.02 x 10
) of stars in the universe. One mole of high school chemistry textbooks would cover the USA to a depth of about 320 km (200 miles).
Water flows over Niagara Falls at about 650,000 kL (172,500,000 gallons) per minute. At this rate it would take 134,000 years for one mole of water
23
drops (6.02 x 10 drops) to flow over Niagara Falls.
Avogadro’s number (6.02 x 1023) is the approximate number of milliliters
8
23 of water in the Pacific Ocean (7 x 10 km3 or 7 x 10 mL).
If one mole of particles the size of sand grains were released by the eruption of Mount St. Helens, they would cover the entire state of
Washington to the depth of a tenstory building.
One mole of marshmallows would cover the USA to a depth of 105,000 km (6500 miles).
If an Avogadro number of pennies were distributed evenly among the human inhabitants of earth, each man, woman, and child would have enough money to spend a million dollars every hour—day and night—and still have over half of it unspent at death.
One guacamole is the amount of taco chip dip that can be made from an
Avogadro number of avocados—plus appropriate quantities of tomatoes, onions, and chili. A train stretching to the North Star and back 21/2 times would be required to transport one guacamole.
Suppose the Greek god Zeus, after observing the Big Bang 15 billion years ago, became bored and decided to count one mole of atoms. Zeus is omnipotent, he can count very fast (one million atoms per second) and, of course, he never sleeps. He has currently completed over threefourths of the task, and will be finished in just another four billion years.
One mole of marbles, each 2 cm in diameter, would form a mountain 116 times higher than Mount Everest. The base of the marble mountain would be slightly larger than the area of the USA.
