How to find the total pressure of a gas mixture?
Understand the Problem
The question is asking how to calculate the total pressure of a gas mixture, which involves understanding the contributions of the individual gases in the mixture based on their partial pressures. This can be approached using Dalton's Law of Partial Pressures.
Answer
P(total) = P₁ + P₂ + P₃ + ...
The final answer is obtained by summing the partial pressures of all gases in the mixture: P(total) = P₁ + P₂ + P₃ + ...

More Information
Dalton's Law of Partial Pressures states that the total pressure exerted by a mixture of non-reacting gases is equal to the sum of the partial pressures of individual gases.
Tips
A common mistake is forgetting to convert all pressures to the same units before summing.
