## Angular Momentum from Bohr’s Formula

The following two example problems outline the steps and information needed to calculate the Angular Momentum from Bohr’s.

L = n*H / (2*pi)

Variables:

- L is the Angular Momentum from Bohr’s Formula ( )
- n is the principal quantum number
- H is the Planck’s constant (6.626*10^-34 (m^2-kg/s))

To calculate the angular momentum, multiply the principal quantum number by Planck’s constant, then divide by 2 times pi.

## How to Calculate Angular Momentum from Bohr’s Formula?

The following steps outline how to calculate the Angular Momentum from Bohr’s.

- First, determine the principal quantum number.
- Next, determine the Planck’s constant.
- Next, gather the formula from above = L = n*H / (2*pi).
- Finally, calculate the Angular Momentum from Bohr’s.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

principal quantum number = 30

Planck’s constant = 6.626*10^-34 (m^2-kg/s)

L = n*H / (2*pi)** **= ?
