![**Problem Statement:**
What is the total pressure if a container contains 66 torr of He gas, 311 torr of N₂ gas, and 46 torr of Ar gas?
**Concept Explanation:**
This problem involves calculating the total pressure of a mixture of gases in a container using Dalton's Law of Partial Pressures. According to Dalton’s Law, the total pressure exerted by a mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases.
**Calculation:**
To find the total pressure, you simply add up the partial pressures of all the gases present.
- Partial pressure of He gas = 66 torr
- Partial pressure of N₂ gas = 311 torr
- Partial pressure of Ar gas = 46 torr
**Total Pressure Calculation:**
\[ \text{Total Pressure} = 66 \, \text{torr} + 311 \, \text{torr} + 46 \, \text{torr} = 423 \, \text{torr} \]
Therefore, the total pressure of the gas mixture is 423 torr.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe3925343-d6c3-4a25-992b-202f02b2b634%2Fcab22ba3-514f-4bd4-b36c-32527bbae427%2Fedkz1q_processed.jpeg&w=3840&q=75)
