1. More Chemical Conversions!!!

2. Chemical Formulas as Conversion Factors
Example:
How many leaves are on 14 clovers?
What do we know?
Each clover has 3 leaves, therefore our conversion factor is 1 clover = 3 leaves
Similarly, a chemical formula tells us equivalences between elements in a compound

3. Converting between Moles of Compounds & Elements
Example:
How many moles of O are in 18 moles of CO2?
Conversion factor
2 mol of 0 = 1 mol of CO2
Your Turn:
How many moles of O are in 1.7 mol of CaCO3?
5.1 mol O

4. Converting between Grams of a Compound & Element
Example:
We have 15 g of NaCl. How many grams of Na do we have?
Conversion factor:
1 mol NaCl = g NaCl
1 mol NaCl = 1 mol Na
1 mol Na = 23 g Na

5. Converting between Grams of a Compound & Element
Your Turn:
Carvone (C10H14O) is the main component of spearmint oil. Find the mass of carbon in g of carvone.
44.3 g C
