Grab a calculator and find your new seat.
Objective: You will be able to: convert between number of
atoms/molecules, moles and mass of any element or compound.
Do now: Search in your notes: a. What is a mole? b. How many atoms/molecules are in
a mole?

Calculators
You’re going to need a calculator to complete homework for the rest of the year.
Come work in here Tues. and Thurs. Buy a $10 scientific calculator
must have scientific notation Use your cell phone (at home).

The Mole
Atoms are so tiny; how do we quantify their masses?
The mole: a unit for amount of substance
In groups of 6.02 x 1023 atoms or molecules
6.02 x 1023 atoms/molecules = 1 mole 6.02 x 1023 atoms/molecules =
Avogadro’s Number

If you react 5.0 grams of oxygen with 5.0 grams of hydrogen, what will you produce?
How many grams will be produced? Will there be oxygen or hydrogen
left over? If so, how much?

Paperclip Mini Lab p. 1-2
You and your partner share on bag of paperclips.
Follow the directions exactly. Be sure to record data as specified by the
directions. To bond, unlink paperclips completely
from the original compounds and then relink them to form the new compound.
Unlink all paperclips and return to bag when you finish!

Law of Conservation of Mass

In a chemical reaction, matter is never created or destroyed.
The number of atoms and the mass of each element of the reactants must be equal to the number of atoms and the mass of element of the products.
![Page 67: C: 4 January 2012](https://reader038.fdocuments.net/reader038/viewer/2022102819/5681694e550346895de0ecb3/html5/thumbnails/67.jpg)
This is shown by placing a coefficient in front of the formula for each compound.
