HW: pp. 233 #1, 2, 4, 5, 6(a), 8(a) 1. A mole is the number of atoms in exactly 12 g of carbon There are x particles in one mole. “Particles” refers to atoms, ions, or molecules. 4.1 mol of nickel(II) and 1 mol of nickel(III) both contain exactly x ions. – (This is like asking “which is heavier: 1 pound of feathers or a 1 pound brick?” They are both 1 pound! Similarly, 1 mol of anything always contains x of whatever is being counted.) mol Pt is more than x atoms. – (This is the same as asking whether 1.11 is more or less that 1.00 because 1.00 mol = x particles is more than 1.00.)

HW Review Continued… 6(a) x ions Fe 3+ 8(a) mol H 2 O We will work through how to answer these questions in today’s lesson!

Focus Questions Today What is a mole, besides a small mammal or a growth on your body, and what is it good for, besides digging holes? Do all moles weigh the same amount?

Analogy: Think of the term dozen... How many doughnuts are in a dozen? How many eggs are in a dozen? How many bricks are in a dozen? How many ostriches are in a dozen?

Get Ready… You’ll know what a “MOLE” is soon

Notes: Introducing the Mole

Counting By Weighing Atoms and molecules are too small to see Atoms and molecules are too small to see We measure out atoms by using a number called the mole!!!! We measure out atoms by using a number called the mole!!!!

What is the mole? (Notes) A mole is the number of atoms in 12 grams of carbon-12. There are x atoms in 12 grams of carbon mole (mol) = x particles.

A mole is very similar to a dozen. But instead of meaning 12 of something, it means 6.02 x of something x = 602,000,000,000,000,000,000,000 Or Six hundred and two sextillion!

1 mole (mol) = 6.02 x This number is a constant. The number of particles in 1 mole is called Avogadro’s Number!

6.02 x Avocado Avogadro

So one mole of......doughnuts is 6.02 x doughnuts... Ostriches is 6.02 x ostriches...oxygen atoms is 6.02 x atoms of oxygen (O)...oxygen molecules is 6.02 x molecules of oxygen (O 2 )

Review- The mole - MEMORIZE 1 mole = 6.02 x particles 6.02 x is called Avogadro’s number The periodic table is based on the molar mass of carbon (C)

THE MOLE -- Why? Why is the mole useful to us as chemists?? Make a dot on your paper with your pencil. Guess how many atoms of Carbon graphite are in that dot. 25 million atoms in that tiny dot!

Say it! How many particles are in 1 mole? – 6.02 x How many atoms are in 1 mole of carbon? How many atoms are in 1 mole of sodium? How many atoms are in 1 mole of sodium? How many atoms are in 1 mole of helium? How many atoms are in 1 mole of helium? How many ducks are in 1 mole of ducks? How many ducks are in 1 mole of ducks?

Conversions particles MOLES

How many particles are in 1 mole of something? 6.02 x To convert from number of moles to number of particles, multiply the number of moles by the conversion factor: x mol

Example 1: How many particles are in 2.00 moles? Multiply 2.00 mol x x particles = x mol

How many particles are in 1 mole of something? 6.02 x To convert from number of particles to number of moles, multiply the number of moles by the conversion factor: 1 mol___ x 10 23

Example 2: How many moles is 3.01 x atoms? Multiply (3.01 x atoms) x __1.00 mole = 0.5 x mole x atoms Scientific notation… 0.5 x mole = 5.0 x mole

1.Draw the Lewis Dot structure for the molecule: HBr 2.How many molecules of HBr are in 2.00 mole of HBr? 3.Which has more atoms: A mole Platinum or a mole of tin?

Random Mole Facts! Since the Earth has a radius of about 6400 km, its volume is approximately m 3. Since about 500 large grapefruit will fit in one cubic meter, it therefore follows that a mole of grapefruit would have approximately the same volume as the Earth. If you had exactly one mole of sheets of paper, you could make one million equal stacks from sea level on the earth that would pass the sun. If you had a mole of pennies, you could give out enough money to everyone in the world so that they could spend a million dollars every hour, day and night, for the rest of their lives.
