Calculate Total Pressure

Formula

The formula to calculate the total pressure is:

\[ \text{P}_{\text{total}} = \sum \text{P}_{\text{partials}} \]

What is Total Pressure?

Total pressure is the sum of the partial pressures of each individual gas in a mixture. It represents the overall pressure exerted by the gas mixture. The concept is based on Dalton's Law of Partial Pressures, which states that the total pressure exerted by a mixture of non-reacting gases is equal to the sum of the partial pressures of each individual gas in the mixture.

Example Calculation

Let's assume we have three gases with the following partial pressures:

Using the formula to calculate the total pressure:

\[ \text{P}_{\text{total}} = 1.2 + 0.8 + 0.5 = 2.5 \text{ atm} \]

The total pressure is 2.5 atm.
