Enter any three state variables to solve the fourth using PV = nRT.
Temperature is calculated in Kelvin.
Tip: Choose the pressure unit first — it sets the R constant.
Reminder: Gas law calculations use Kelvin (K).

Compare two gas states under a chosen process using the universal form:
P₁V₁/(n₁T₁) = P₂V₂/(n₂T₂). Temperature is calculated in Kelvin.

mol
Relate density, molar mass, pressure, and temperature
using the ideal gas relationship:
M = dRT / P and d = PM / RT
Gas calculations require Kelvin.

g/L
Explore gas mixtures using:
Dalton: Ptotal = ΣPi, Xi = Pi/Ptotal Moles: Xi = ni/ntotal Ideal (component): PiV = niRT

Full Reaction Engine (Ideal gas, constant V & T)
Enter reactants/products (with coefficients) and initial amounts (mol or partial pressure).
The solver finds the limiting reactant, reaction extent ξ, final moles, partial pressures, and total pressure.
L
K
Uses ideal gas law: P = nRT/V

Used only to interpret yield from measured product (if provided).
%
Leave blank if you enter an actual product amount.
If provided, it overrides percent yield and computes yield automatically.
