The problem you have uploaded involves a gas cylinder containing nitrogen gas under pressure, and we are tasked with determining the final volume of gas after it is allowed to escape. Here’s how we can solve it:

### Given:
- Diameter of the cylinder: 3.6 cm (radius = 1.8 cm)
- Height of the cylinder: 14 cm
- Gas pressure inside the cylinder: 20.4 atm

We can use the **ideal gas law** and the formula for the volume of a cylinder to solve this.

First, let's calculate the **volume of the cylinder** using the formula:
\[
V = \pi r^2 h
\]
where:
- \(r = 1.8 \, \text{cm} = 0.018 \, \text{m}\) (radius in meters),
- \(h = 14 \, \text{cm} = 0.14 \, \text{m}\),
- \(\pi \approx 3.1416\).

Then, we need to apply the gas laws to figure out how much gas will escape. Since the gas is initially at 20.4 atm and expands to atmospheric pressure (which is 1 atm), the volume at the end can be found using:
\[
P_1 V_1 = P_2 V_2
\]
where:
- \(P_1 = 20.4 \, \text{atm}\),
- \(V_1\) is the volume of the cylinder (which we’ll calculate),
- \(P_2 = 1 \, \text{atm}\),
- \(V_2\) is the final volume (the unknown).

Let me calculate this step-by-step.### Calculations:
1. **Volume of the cylinder:** \(0.0001425 \, \text{m}^3\) (or \(142.5 \, \text{cm}^3\)).
2. **Final volume of nitrogen gas at 1 atm:** \(2.91 \, \text{liters}\).

So, after the gas escapes and expands to atmospheric pressure, the total volume of nitrogen gas is **2.91 liters**.

**Tip:** Always make sure to convert units consistently, especially when dealing with different measurement systems like meters and centimeters.

A gas storage cylinder in an ordinary chemical laboratory measures 3.6 cm wide and 14 cm high. Contents: N2 gas, Pressure: 20.4 atm. If the cylinder is opened and the gas allowed to escape into a large empty plastic bag, what will be the final volume of nitrogen gas, including what's collected in the plastic bag and what's left over in the cylinder?
