Note that the NUMBER is always the same, but the MASS is very different! Mole is abbreviated molġ0 Atomic Mass (amu) What is the atomic mass of: Na Ca Pb If we were able to count atoms at the rate of 10 million per second, it would take about 2 billion years to count the atoms in one mole.ġ mole of cookies = 6.02 X 1023 cookies 1 dozen cars = 12 cars 1 mole of cars = 6.02 X 1023 cars 1 dozen Al atoms = 12 Al atoms 1 mole of Al atoms = 6.02 X 1023 atomsĩ How does the mass of a dozen cars compare to the mass of a dozen cookies? If you had Avogadro's number of unpopped popcorn kernels, and spread them across the United States of America, the country would be covered in popcorn to a depth of over 9 miles. It would take you over 19 million years to spend a mole of dollars.ħ Just How Big is a Mole? Enough soft drink cans to cover the surface of the earth to a depth of over 200 miles. One mole = 6.02 x 1023 particles Know how to determine molar mass of a molecule and how to convert to moles, # of particles, or volume of gas at STP.ġ dozen = 12đ ream = gross = 144 1 mole = 602,000,000,000,000,000,000,000 6.02 X 1023 (in scientific notation)Ĥ Amedeo Avogadro (1776 – 1856) -studied quantities of gases & discovered that no matter what the gas was the same number of molecules are presentĥ Just How Big is a Mole? How long do you think it will take to count to 6.02x1023?Ħ Just How Big is a Mole? If you spent a billion dollars a second, Presentation on theme: "The Mole 6.02 x 1023."- Presentation transcript:Ģ Standard/Objective Know the quantity one mole is set by defining one mole of carbon 12 atoms to have a mass of exactly 12 grams.
