Question
**Homework Problem: Gas Mixture Pressure Calculation** 

**Chapter 5 HW #2**

**Points: 1**

**Instructions:**

Enter your answer in the provided box.

**Problem Statement:**

After 0.600 L of Ar at 1.33 atm and 213°C is mixed with 0.200 L of O₂ at 401 torr and 131°C in a 400 mL flask at 24°C, what is the pressure in the flask?

**Answer Box:**

[          ] atm

---

**Explanation:**

This question requires you to calculate the final pressure of a gas mixture in a flask. It involves:

1. Understanding gas laws and how they apply to mixtures.
2. Converting units where necessary (e.g., torr to atm).
3. Applying the ideal gas law and potentially the combined gas law to solve for the unknown pressure.

Expert Solution
Step 1

In the given question there are 2 stages initial and final points.

                    Initial                        Final
              Pressure= ?               Pressure= 401 torr=401760 atm
          Volume V1=0.6 L         Volume V2=0.2 L

 Temperature T1= 213C

T1= 213+ 273= 486 K

Temperature T2= 131C

T2= 131+ 273= 404 K

On applying the equation,

PVTInitial=PVTFinal
