📘 Practical Examples of Usage
Example 1: Finding Pressure (P)
A gas has:
- Volume = 10 L
- Moles = 2 mol
- Temperature = 300 K
Using the tool:
- P = (nRT) / V
- P = (2 × 0.0821 × 300) / 10
- P = 4.926 atm
✔ Final Answer: 4.926 atm
Example 2: Finding Volume (V)
Given:
- Pressure = 1.5 atm
- Moles = 1 mol
- Temperature = 273 K
Using the tool:
- V = (nRT) / P
- V = (1 × 0.0821 × 273) / 1.5
- V = 14.94 L
✔ Final Answer: 14.94 liters
Example 3: Finding Temperature (T)
Given:
- Pressure = 2 atm
- Volume = 5 L
- Moles = 0.5 mol
Using the tool:
- T = (PV) / (nR)
- T = (2 × 5) / (0.5 × 0.0821)
- T = 243.24 K
✔ Final Answer: 243.24 Kelvin
