Outcomes – January 30-Feb1. 1. Receive two mole bucks for having the practice quiz done prio r to the quiz! 2. Revisit naming and formula writing, figuring out how to read the flow chart given 3. Learn what a mole is and why we use the unit “mole” to describe quantity of atoms and molecules!.
2 FeCl3 + 1 Be3(PO4)2 --> 3 BeCl2 + 2 FePO4
Now, do the same for the products side.
What is it called when the number and mass on both sides of the equation are equivalent to each other?
Li2SO4 Al(OH)3 N2O3
CCl4 Mg3(PO4)2 BeCl2
Pair = 2
Names associated with an amount

A 1 Liter bottle of water contains 55.5 moles H2O.
A 5 pound bag of sugar contains 6.6 moles of C12H22O11.
There are 3 types of moles that live underground in North America: Eastern Mole, Hairy-Tailed Mole and Star-Nosed Mole.
You’ve seen this before, because when working with a large number of objects, it’s frequently handy to use units that are easier to work with.
The mole (mol) is the amount of a substance that
contains as many elementary entities as there
are atoms in exactly 12.00 grams of 12C
1 mol = NA = 6.0221367 x 1023
Avogadro’s number (NA)
Molar mass is the mass of 1 mole of in grams
1 amu = 1 g/mol
These numbers are proportional
Na:22.99 grams x1 atom = 22.99 g/mol
Cl: 35.45 grams x 1 atom =35.45 g/mol
Total: 58.44 grams/mol
Mg: 24.31 grams x 1 atom = 24.31 grams/mol
N: 14.01 grams x 2 atoms = 28.02 grams/mol
O: 16.00 grams x 6 atoms = 96.00 grams/mol
Total: 148.33 grams/mol
6.02 x 1023
6.022 x 1023 atoms K
1 mol K
39.10 g K
How many atoms are in
0.551 g of potassium (K) ?
1 mol K = 39.10 g K
1 mol K = 6.022 x 1023 atoms K
