What is Dalton's Law of Partial Pressures?

Back

Dalton's Law states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of each individual gas.

How do you calculate the total pressure of a gas mixture?

Back

Total pressure (P_total) = P_1 + P_2 + P_3 + ... + P_n, where P_1, P_2, ..., P_n are the partial pressures of the individual gases.

What is a partial pressure?

Back

Partial pressure is the pressure that a single gas in a mixture would exert if it occupied the entire volume alone.
