User Guide
This tool will calculate any parameter from the equation for the ideal gas law PV=nRT, which includes the pressure, volume, amount of substance and temperature of a quantity of gas.
Formulas
The Ideal gas law is explained with math in the following way.
Using SI units for each parameter, the multiplying together of pressure and volume will equal the multiplying together of the amount of substance, the temperature and the ideal gas constant.
P · V = n · R · T
The formulas used by this ideal gas law calculator to determine each individual parameter are:
P = n · R · T / V
V = n · R · T / P
n = P · V / (R · T)
T = P · V / (n · R)
Symbols
- P = Pressure of gas
- V = Volume of gas
- n = Amount of substance of gas
- R = Ideal gas constant (8.31446261815324 J⋅K-1⋅mol-1)
- T = Temperature of gas
Pressure (P)
This is the absolute pressure of the gas.
Volume (V)
This is the total volume occupied by the gas.
Amount Of Substance (n)
This is the number of gas atoms or molecules that are included in the quantity of gas.
Temperature (T)
This is the temperature of the gas.
