Converting Moles and Grams
Aluminum is often used for the structure of light-weight bicycle frames. How many grams of Al are in 3.62 moles of Al? a

1 mole Al = ?

1 mole Al = ? 1 mole Al = 27.0 g Al

What are the conversion factors?
1 mole Al = 27.0 g Al

What are the conversion factors?
1 mole Al = 27.0 g Al 27.0g Al or mol Al 1 mol Al g Al

Lab Activity Mole Worksheet 2 Mole Worksheet 2 is a lab exercise.
Notice that there is a front and a back to the worksheet. The answers on the back have been given however you need to show your work as factor label problems to get credit. You and your lab partner need to turn in one copy of the worksheet by the end of the period.
