## BET Surface Area Formula

The following two example problems outline the steps and information needed to calculate the BET Surface Area.

**BET = #M * AM**

- Where BET is the BET Surface Area ( )
- #M is the amount of molecules in the monolayer
- AM is the space occupied by one molecule

## How to Calculate BET Surface Area?

The following example problems outline how to calculate BET Surface Area.

Example Problem #1:

- First, determine the amount of molecules in the monolayer.
- The amount of molecules in the monolayer is given as: 100.

- Next, determine the space occupied by one molecule.
- The space occupied by one molecule is provided as: 1.5.

- Finally, calculate the BET Surface Area using the equation above:

BET = #M * AM

The values provided above are inserted into the equation below and computed.

BET =100 *1.5 = 150.00

Example Problem #2:** **

For this problem, the variables required are provided below:

amount of molecules in the monolayer = 600

space occupied by one molecule = 23

Test your knowledge using the equation and check your answer with the calculator..

BET = #M * AM** = ?**
