At a constant temperature, 250 mL of argon at 760 mm pressure and 600 mL of nitrogen at 500 mm pressure are put together in a one litre flask. Calculate the final pressure.

Explanation

To solve the problem of finding the final pressure when 250 mL of argon at 760 mm pressure and 600 mL of nitrogen at 500 mm pressure are mixed in a 1-liter flask, we can use the concept of partial pressures and the ideal gas law. Here’s a step-by-step solution:

### Step 1: Identify the Given Values
- For argon (Ar):
- Volume (V1) = 250 mL
- Pressure (P1) = 760 mmHg
- For nitrogen (N2):
- Volume (V2) = 600 mL
