# Dalton's Law of Partial Pressures

### From Conservapedia

**Dalton's law of partial pressures** states that when two or more ideal gases are mixed together, the total pressure (P) of the mixture is equal to the sum of the pressures of each individual gas. ^{[1]} Represented mathematically:

- P
_{total}= P_{1}+ P_{2}+ P_{3}+ ... + P_{n}

The pressure of an individual gas can be found if the total pressure and concentration (y_{i}) are known:

- P
_{i}= X_{i}P_{total}
