Big Ideas
- The total pressure exerted by a mixture of gases is the sum of the pressures each gas would exert if it were the only gas present.
- Dalton's law of partial pressure enables the calculation and prediction of individual gas contributions in a mixture, which is key to understanding ideal gas behavior.
