Enter the mass of compound 1 (kg), the mass of compound 2 (kg), and the total volume of composite (m^3) into the Composite Density Calculator. The calculator will evaluate and display the Composite Density. 

Composite Density Formula

The following formula is used to calculate the Composite Density. 

CD = (m1+m2) / V
  • Where CD is the Composite Density (kg/m^3)
  • m1 is the mass of compound 1 (kg) 
  • m2 is the mass of compound 2 (kg) 
  • V is the total volume of composite (m^3) 

To calculate the composite density, sum the mass of both compounds, then divide by the total combined volume.

How to Calculate Composite Density?

The following example problems outline how to calculate Composite Density.

Example Problem #1

  1. First, determine the mass of compound 1 (kg).
    1. The mass of compound 1 (kg) is given as 5.
  2. Next, determine the mass of compound 2 (kg).
    1. The mass of compound 2 (kg) is calculated as: 10.
  3. Next, determine the total volume of composite (m^3).
    1. The total volume of composite (m^3) is found to be: 2.
  4. Finally, calculate the Composite Density using the formula above: 

CD = (m1+m2) / V

Inserting the values from above yields: 

CD = (5+10) / 2 = 7.5 (kg/m^3)

Example Problem #2

The variables needed for this problem are provided below:

mass of compound 1 (kg) = 5

mass of compound 2 (kg) = 93

total volume of composite (m^3) = 10

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

CD = (m1+m2) / V = (kg/m^3)
