Mole to Mole Conversions

- Coefficients in balanced equations tell us the number of moles reacted or produced. 

- They can also be used as conversion factors.

Rule for conversion:

*WHAT YOU NEED OVER WHAT YOU HAVE

*Coefficients have to be in moles.

Example 1: 

A + 3B > 2C

6 mol      ? mol

6 mol B x 1A (what we need)= 2 mol of A

                 --------------------------  

                 3B (what we have)

Example 2:

A + 7 B > 9c

       -   

       2    

0.25 mol of A x 3.5 B  = 0.88 mol

                          ------

                          1A
