2.) a. weeks  days b. 1 week is equal to 7 days 1 week/7 days

29. Part 1: Using Our Schema
Notes: 2 b. 7 days in 1 week

30. Notes
To convert between units, we need to know the relationship between both our given and desired units. We call this relationship a conversion factor.

31. Notes For example: 100 pennies = 1 dollar
This conversion factor works because it represents the same amount of money.

32. Notes
A conversion factor represents an equal quantity so therefore, there should be an equal sign between both units.

33. Notes We can also write a conversion factor as a fraction.
For example:
10 dimes
1 dollar

34. Practice
3. Same length 1 foot = 12 inches 1 foot/12 inches 4. Same length 1 yard = 3 feet 1 yard/3 feet

35. Practice
5. Same amount of time 60 seconds = 1 minutes 60 seconds/1 minute 6. Same amount of time 24 hours = 1 day 24 hours/1 day

36. Notes
We can use a structure called a t –chart to help us convert units using the correct conversion factors.

37. Notes Getting Started: Underline your givens, circle your desired.
Write in the given and desired units.
Write in the conversion factor. The conversion factor will “connect” the two units of the given and the desired.

38. Notes Solving the T-Chart
The conversion fraction goes in the same column.
If the number is in the same row of the “t”, then multiply.
If the number is in the bottom row, divide.
Cancel out units and write the remaining unit with the answer.

39. Example 5 kilometers to meters. Given: 5 kilometers Conversion Factor:
1 km = 103 m
1 kilometer
meters
5000 m

Conversion

45. The Mole
It is important for scientists to know how many atoms or molecules are entering a chemical reaction.
Atoms and molecules are really tiny, so how can we count them?

46. The Mole
Sometimes we group items into manageable units for counting purposes:
Example:
Count eggs with a dozen = 12 eggs
Count sheets of paper with a ream = 500 sheets
Count age with a year = days
These units are too small for atoms! A ream of atoms would be too small for the human eye!

47. The Mole
Chemists use a different unit for counting atoms: THE MOLE.

48. The Mole
Not these types of moles!

49. The Mole Just as 1 dozen = 12 items, 1 mole = 6.022 x 1023 items.
In standard notation we write this as: 602,200,000,000,000,000,000,000
That’s a huge number!

50. The Mole Let’s put this in perspective…
If you went to the store and bought a dozen donuts, you would need a box just large enough to hold 12 donuts.
>

51. The Mole
If you went to the store and bought a mole of donuts, you would need a box 1/2 the size of the earth!

Using the value of a mole we can create TWO values for T-Charts when converting:
When going from Moles to Molecules/Atoms
When going from Molecule/Atoms to Moles
Given Unit (Moles)
6.02 x 1023 atoms/molecules
1 mole
Given Unit (Molecules/Atoms)
1 mole
6.02 x 1023 molecules/atoms

60. The Mole
A mole of them -- or x 1023 molecules!

61. Example or Whiteboard Practice
When looking at the problem FIRST do the following:
Underline the given value
Circle the desired value
Set up your T-Chart just like yesterday
Desired unit on TOP of conversion factor
Given unit at the BOTTOM of conversion factor
Cancel out units
Circle your final answer and include YOUR UNITS!!!!

62. The Mole: Atom to Mole
How many atoms are in 4.5 moles of magnesium ribbon?
Ans: 2.7 x 1024 atoms
4.5 moles
6.02 x 1023 atoms
1 mole

63. Thursday, October 30th, 2014

75. Demo
Observe the two beakers in the front: one has sugar, and one has salt.
How many moles do you think are in each of the beakers?
They both only have ONE MOLE each!
How can one mole be a different amount for each substance?

76. Molar mass
Molar mass is the mass of one mole of a certain element or compound
We find these values from the periodic table.
Units of molar mass is grams per mole
g/mol

77. Molar mass
For a compound, we add together the masses of each element in the compound.
Ex: Mass of H2O= Mass of 2 hydrogen + mass of oxygen
Mass of H2O= 2(1.01 g) g = g

78. Whiteboard Practice Use the periodic table to find the molar massNa Cl
H2O
NH3
= 14.0 g/mol
=22.99 g/mol
= g/mol
=18 g/mol
=17 g/mol

79. Check in: What is the molar mass of NaCl?
Answer:
~58.44 g/mole

80. What is the molar mass of CO2?

81. The Molar Mass and Number of Particles in One-Mole Quantities
Substance Molar Mass Number of Particles in One Mole
Carbon (C) g x 1023 C atoms
Sodium (Na) g x 1023 Na atoms
Iron (Fe) g x 1023 Fe atoms
NaF (preventative g x 1023 NaF formula units
for dental cavities)
CaCO3 (antacid) g x 1023 CaCO3 formula units
C6H12O6 (glucose) g x 1023 glucose molecules
C8H10N4O2 (caffeine) g x 1023 caffeine molecules

82. Mole Island Mass 1 mol = molar mass (in g) (g) Particle (atoms)
1 mol = 6.02 x 1023 particles

83. The Mole
Using the value of a mole we can create TWO values for T-Charts when converting:
When going from Moles to grams
When going from grams to Moles
Given Unit (Moles)
Molar mass (grams)
1 mole
Given Unit (grams)
1 mole
(periodic table) grams

84. The Mole
Back to the demo: How many what is the mass of the salt if there is one mole?
Molar mass of NaCl is Na + Cl
Molar mass of NaCl = 58.44
58.44 grams
1 mole
1 mole NaCl
= grams NaCl

85. 2. How many grams are in 5.69 moles of uranium?( )
238.0 g
5.69 mol
= 1,354 g U
1 mol
= x 103 g U
3. How many moles are in 8.9 grams of neon? ( )
