KDA from G/mol Formula

The following two example problems outline the steps and information needed to calculate the KDA from G/mol.

KDA = g/mol /1000

Variables:

  • KDA is the KDA from G/mol (kilo-daltons)
  • g/mol is the total number of grams per mole (g/mol) 

To calculate KDA from G/mol, divide the grams per mole by 1000.

How to Calculate KDA from G/mol?

The following steps outline how to calculate the KDA from G/mol.

  1. First, determine the total number of grams per mole (g/mol). 
  2. Next, gather the formula from above = KDA = g/mol /1000.
  3. Finally, calculate the KDA from G/mol.
  4. 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.

total number of grams per mole (g/mol) = 500

KDA = g/mol /1000 = ?
