Enter the principal quantum number and the Planck’s constant into the Angular Momentum from Bohr’s Calculator. The calculator will evaluate the Angular Momentum from Bohr’s. 

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.

  1. First, determine the principal quantum number. 
  2. Next, determine the Planck’s constant. 
  3. Next, gather the formula from above = L = n*H / (2*pi).
  4. Finally, calculate the Angular Momentum from Bohr’s.
  5. 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) = ?
