What is a Mole? In chemistry it is not a cute animal that lives in the ground. A mole is the SI unit that describes the amount of a substance. One mole = 6.02 x 1023 objects In chemistry the objects are atoms and molecules. Let’s think how large a mole really is... Let’s think of things we see everyday! A mole of marshmallows would cover the planet Earth 12 miles high. A mole of seconds would last so long the universe would die out before it was done! 1 Mole of marbles would fill the entire Grand Canyon and there would still be enough left over to displace all the water in Lake Michigan and a few other lakes! Computers can count at the rate of over 800 million counts per second. At this 6.02 x 1023. rate it would take a computer over 25 million years to count to A mole of hockey pucks would be equal to the mass of the Moon. Assuming that each human being has 60 trillion body cells (6.0 x 1013) and the Earth's population is 6 billion (6 x 109), the total number of living human body cells on the Earth at the present time is 3.6 x 1023or a little over half of a mole.
