Total Pressure Formula
The following formula is used to calculate the Total Pressure.
Ptotal = Σ Ppartials
- Where Ptotal is the Total Pressure (atm)
- Ppartials are the partial pressures of each gas (atm)
To calculate total pressure, simply sum the partial pressures of each gas.
How to Calculate Total Pressure?
The following two example problems outline how to calculate the Total Pressure.
Example Problem #1:
- First, determine the partial pressure of each gas (atm). In this example, the partial pressure of each gas (atm) is given as 12,35,6.
- Finally, calculate the Total Pressure using the equation above:
Ptotal = Σ Ppartials
Inserting the values from above and solving the equation with the imputed values gives:
Ptotal =12+35+6 =53 (atm)
Example Problem #2:
Using the same process as above, first define the variables required by the formula. In this case, these values are:
partial pressure of each gas (atm) = 5,6,87
Entering these values yields:
Ptotal = 5+6+87 = 98 (atm)
