**Question 10 of 13**

At 25.0° C, a 10.00 L vessel is filled with 5.25 moles of Gas A and 3.10 moles of Gas B. What is the total pressure in atm?

---

**Explanation**

This question involves calculating the total pressure in a container with a mixture of gases using the ideal gas law. The steps to solve this include:

1. **Calculate the total moles of gas** by adding the moles of Gas A and Gas B: 
   
   Total Moles = 5.25 moles of Gas A + 3.10 moles of Gas B

2. **Use the Ideal Gas Law equation**: \( PV = nRT \)

   - \( P \) is the pressure in atm,
   - \( V \) is the volume in liters,
   - \( n \) is the number of moles,
   - \( R \) is the ideal gas constant (0.0821 atm·L/mol·K),
   - \( T \) is the temperature in Kelvin (Convert 25.0°C to Kelvin by adding 273.15).

3. **Solve for the pressure \( P \)** using the total moles and the given conditions.

The keypad below the question allows for input of the calculated pressure value.
