- How many moles of Al are produced by 5 moles of AlCl3?
5 moles
This conversion factor is used to convert between substances, IE switch from moles A to moles B
Mole Ratio
If we are converting from moles of A to grams of B, what step can we skip in our flowchart!?
Step 1 OR you do not need to convert from grams of A to moles of A
Describe the theoretical yield!
How much mass our stoichiometry tells us we should make
