I need help with problem A in my chemistry class please.

 

**Exercise 5.40 - Enhanced: Pressure Calculation with Ideal Gas Law** --- **Exercise 5.40 - Enhanced - with Feedback** *Part A* **Problem Statement:** Determine the pressure in a 20.0 L cylinder filled with 38.5 g of oxygen gas at a temperature of 343 K. Express your answer to three significant figures with the appropriate units. **Input Fields:** - P = _______ [Value] [Units] **Buttons:** - [Submit] - [Request Answer] **Links:** - Review - Constants - Periodic Table **Navigation:** - [Next] **Additional Features:** - Provide Feedback --- **Instructions:** Use the Ideal Gas Law \( PV = nRT \) to calculate the pressure: 1. Convert the mass of oxygen to moles using the molar mass of O₂. 2. Insert the values into the Ideal Gas Law formula. 3. Calculate for pressure (P) and ensure the units are correct. 4. Submit your answer for evaluation. For further assistance, refer to Section 6.4 and utilize the provided constants and periodic table links.
