What elements do I need to know? Elements 1-20 on Periodic Table! Quiz: Friday! Know: Name  Symbol AND Symbol  Name SPELLING COUNTS!!!

Take out your “Notes: Introduction to the T-Chart” Sheet

Think Read and answer questions 1 & 2.

Part 1: Using Our Schema 1.) a. days  weeks b. 7 days in 1 week

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

Part 1: Using Our Schema 2.) a. weeks  days b. 1 week is equal to 7 days 1 week/7 days

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

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.

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

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

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

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

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

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

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.

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.

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

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?

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 = 365.25 days These units are too small for atoms! A ream of atoms would be too small for the human eye!

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

The Mole Not these types of moles!

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!

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. ---------->

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! ------> 0.5 x !!!

The Mole 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

The Mole A mole of them -- or 6.022 x 1023 molecules!

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!!!!

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?

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

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) + 16.00 g = 18.02 g

Whiteboard Practice Use the periodic table to find the molar mass Na Cl H2O NH3 = 14.0 g/mol =22.99 g/mol = 35.45 g/mol =18 g/mol =17 g/mol

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

What is the molar mass of CO2?

The Molar Mass and Number of Particles in One-Mole Quantities Substance Molar Mass Number of Particles in One Mole Carbon (C) 12.0 g 6.02 x 1023 C atoms Sodium (Na) 23.0 g 6.02 x 1023 Na atoms Iron (Fe) 55.9 g 6.02 x 1023 Fe atoms NaF (preventative 42.0 g 6.02 x 1023 NaF formula units for dental cavities) CaCO3 (antacid) 100.1 g 6.02 x 1023 CaCO3 formula units C6H12O6 (glucose) 180.0 g 6.02 x 1023 glucose molecules C8H10N4O2 (caffeine) 194.0 g 6.02 x 1023 caffeine molecules

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

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

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 = 58.44 grams NaCl

2. How many grams are in 5.69 moles of uranium? ( ) 238.0 g 5.69 mol = 1,354 g U 1 mol = 1.35 x 103 g U 3. How many moles are in 8.9 grams of neon? ( ) 1 mol 8.9 g Neon = 0.44 mol Ne 20.2 grams Ne 4. How many moles are in 421 g of Sodium? ( ) 1 mol 421 g = 18.3 grams Na 22.99 g
