In science it is common to look at extremely large numbers. Consider the following number.
6 022 141 500 000 000 000 000 000
This number is the number of particles found in 12 grams of carbon-12. It is known as Avagadro’s number named in honor of the chemist Amedeo Avagadro. Although the number seems ridiculous it is extremely important to chemists as it represents the number of particles found in 1 gram mole of any substance.
