In a sealed container, the partial pressures of three gases,...

Question Analysis
This question assesses the student's ability to apply Dalton’s Law of Partial Pressures to determine the partial pressure of a fourth gas in a mixture when the total pressure and the partial pressures of the other three gases are known.

Key Concept Explanation
Dalton’s Law of Partial Pressures states that the total pressure of a gas mixture is the sum of the partial pressures of each individual gas. To find the partial pressure of an unknown gas, subtract the known partial pressures from the total pressure.

Step-by-step Solution
1. Identify the given values: Total pressure , partial pressure of argon , partial pressure of helium , and partial pressure of neon .
2. Use the formula for the total pressure:
