What Is a Free Ideal Gas Law Calculator?
A Free Ideal Gas Law Calculator is an online chemistry and physics tool that calculates the relationship between a gas’s pressure, volume, amount, and temperature using the Ideal Gas Law.
PV=nRTPV = nRT
P=1(0.082057)(298)24=1.019 atmP=\frac{\text{1}(\text{0.082057})(\text{298})}{\text{24}}=\text{1.019}\,\mathrm{atm}P=241(0.082057)(298)=1.019atm

Ideal Gas Law Formula
PV=nRTPV=nRT
Where:
- P = pressure
- V = volume
- n = amount of gas in moles
- R = ideal gas constant
- T = absolute temperature in Kelvin
The calculator can rearrange the equation to find any unknown variable.
What Can the Calculator Calculate?
A free Ideal Gas Law Calculator can determine:
- Pressure (P)
- Volume (V)
- Number of moles (n)
- Temperature (T)
- Gas constant values based on the selected units
Example
Suppose a gas has:
- Pressure = 1 atm
- Volume = 22.414 L
- Temperature = 273.15 K
- R = 0.082057 L·atm/(mol·K)
Using: n=PVRTn=\frac{PV}{RT}
the result is approximately:
n = 1 mole
