How to Use the Calculator
- Enter the number of moles (n) of the gas you have.
- Specify the temperature (T) in degrees Celsius (°C). The calculator will convert this to Kelvin (K) for the calculation.
- Enter the pressure (P) in atmospheres (atm). The default is 1 atm (standard pressure).
- The gas constant (R) is fixed at 0.0821 L·atm/(mol·K) for this calculator.
- Click the "Calculate" button to compute the volume in liters.
- The result will be displayed in the "Result" section.
Working Principle
The calculator uses the ideal gas law equation to calculate the volume of a gas:
V = nRT/P
Where:
- V = Volume of the gas in liters
- n = Moles of the gas
- R = Ideal gas constant (0.0821 L·atm/(mol·K))
- T = Temperature in Kelvin
- P = Pressure in atmospheres
Example
If you have 2 moles of an ideal gas at 25°C and 1 atm pressure, the volume would be:
- n = 2 moles
- T = 25°C = 25 + 273.15 = 298.15 K
- P = 1 atm
- R = 0.0821 L·atm/(mol·K)
- V = (2 mol × 0.0821 L·atm/(mol·K) × 298.15 K) / 1 atm = 49.1 L
