Ideal Gas Law Solver

Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
In this Demonstration, you can solve for any of the four variables in the ideal gas law, , given the other three. In SI units the pressure
is expressed in pascals (Pa), equal to
. Since one standard atmosphere equals 101.325 kPa, the SI pressure units are given in kPa. Volume
is in
, temperature
in K, and number of moles
in mol. The universal gas constant
J/K mol (it is divided by 1000 so
comes out in kPa).

Details
Snapshot 1: traditional definition of standard state: 1 atm, 0°C; gives well-known molar volume, 22.4 L
Snapshot 2: an alternative new definition, with kPa = 1 bar
Snapshot 3: closer to room temperature, °C
