## Activity: Moles Practice

Example Conversion Factors
The Mole 6.02 × 1023 = 1 mol so
 ``` 6.02 × 1023 ------------ or 1 mol ``` ``` 1 mol ------------ 6.02 × 1023 ```
 For the element carbon (C) 6.02 × 1023 = 1 mol = 12.011 g so: ``` 6.02 × 1023 atoms ------------ or 1 mol ``` ``` 1 mol ------------ or 6.02 × 1023 atoms ``` ``` 1 mol ------------ or 12.011 g ``` ``` 12.011 g ------------ 1 mol ``` For the elements carbon (C) and hydrogen (H) in C3H8… ``` 3 mol carbon atoms ------------------ or 1 mol C3H8 ``` ``` 1 mol C3H8 ------------------ or 3 mol carbon atoms ``` ``` 8 mol hydrogen atoms ------------------ or 1 mol C3H8 ``` ``` 1 mol C3H8 ------------------ 8 mol hydrogen atoms ```
