Gravimetric Factor Formula

The following two example problems outline the steps and information needed to calculate the Gravimetric Factor.

GF = CD / ND

Variables:

  • GF is the Gravimetric Factor ( )
  • CD is the concentration of current dye used (g/mL) 
  • ND is the concentration of new dye (g/mL) 

To calculate the gravimetric factor, divide the concentration of the current dye by the concentration of the new dye.

How to Calculate Gravimetric Factor?

The following steps outline how to calculate the Gravimetric Factor.

  1. First, determine the concentration of current dye used (g/mL). 
  2. Next, determine the concentration of new dye (g/mL). 
  3. Next, gather the formula from above = GF = CD / ND.
  4. Finally, calculate the Gravimetric Factor.
  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.

concentration of current dye used (g/mL) = 30

concentration of new dye (g/mL) = 50

GF = CD / ND = ?
