The Ideal Gas Law
Calculate pressure, volume, temperature, and density relationships using the Ideal Gas Law. This calculator helps solve problems involving ideal gases using the fundamental equations: pV = nRuT, pV = mRT, and p = ρRT.

Equations
Primary Ideal Gas Law:
- pV = nRu T (using moles)
- pV = mRT (using mass)
- p = ρRT (using density)
Where:
- p = absolute pressure
- V = volume
- n = number of moles
- Ru = universal gas constant = 8.3145 J/(mol·K)
- m = mass
- R = individual gas constant (depends on gas)
- T = absolute temperature
- ρ = density = m/V
For a given quantity of gas:
- p₁V₁/T₁ = p₂V₂/T₂
Density calculation:
- ρ = p/(RT)
