Calculate theoretical volume from mass and density (V = m/d), or find theoretical mass or density, plus ideal gas volume in liters at STP.

Nominal density preset
Approximate starting values; enter the density for your actual composition and conditions.

Theoretical Volume Formula

The following formula is used to calculate the Theoretical Volume. 

Vt = m / d
  • Where Vt is the Theoretical Volume (m3)
  • m is the mass (kg) 
  • d is the theoretical density (kg/m3) 

To calculate a theoretical volume, choose Volume from mass and density, enter the two known quantities and select Calculate. For porosity, use bulk and true density for the same specimen: porosity = (1 โˆ’ bulk density / true density) ร— 100. Mixture volume assumes additive component volumes. Ideal gas modes use V = nRT/P with absolute pressure and temperature above 0 K.

How to Calculate Theoretical Volume?

The following example problems outline how to calculate Theoretical Volume.

Example Problem #1:

  1. First, determine the mass (kg).
    1. The mass (kg) is given as 50.
  2. Next, determine the theoretical density (kg/m3).
    1. The theoretical density (kg/m3) is provided as 10.
  3. Finally, calculate the Theoretical Volume using the equation above: 

Vt = m / d

The values given above are inserted into the equation below:

Vt = 50 / 10 = 5 (m3)

Example Problem #2: 

The variables needed for this problem are provided below:

mass (kg) = 60

theoretical density (kg/m3) = 5

Entering these values and solving gives:

Vt = m / d = 12 (m3)
