![**Experiment Instructions and Ideal Gas Law Calculation**
**Objective:**
To conduct an experiment by using a gas pump to inject gas into a chamber.
**Procedure:**
1. Use the gas pump to add gas into the chamber. Pump between 3 and 7 times.
2. Adjust the temperature to a range between 100 K and 500 K using the fire/ice bucket at the bottom.
3. Maintain the chamber width at 10.0 nm (adjust using the handle on the left of the chamber) and do not open the chamber to release gas molecules.
**Ideal Gas Law Calculation:**
The formula to calculate moles of gas is:
\[ PV = nRT \]
Where R = 0.0821.
**Measurements:**
- **Pressure:**
The pressure is shown on the circular instrument located at the top right of the chamber. It is measured in atmospheres (atm).
- **Volume:**
Volume is calculated in nm³ by multiplying width, height, and depth of the chamber. The height is always 10.0 nm, and the depth is always 1.00 nm. You can adjust the width to 10.0 nm or 15.0 nm. Therefore, the volume is calculated as follows:
\[ \text{Volume} = \text{Width} \times 10.0 \, \text{nm} \times 1.00 \, \text{nm} \]
Assume that the resulting volume in nm³ is directly used as liters (L) for Ideal Gas Law calculations.
- **Temperature:**
Temperature is measured using the thermometer, already provided in Kelvin.
- **Quantity:**
For this experiment, calculate the number of moles (n) under each scenario using the Ideal Gas Law formula.
When solving for moles (n) using the Ideal Gas Law:
\[ n = \frac{PV}{RT} \]
Where:
- P is pressure in atm,
- V is volume in liters,
- R is the gas constant (0.0821),
- T is temperature in Kelvin.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6f1e8666-0358-4f82-8394-bfae4d254ad0%2F8464cf5e-61c2-413d-bb08-26dc46c50100%2Fjzp7qb_processed.jpeg&w=3840&q=75)
