Universal Gas Law Calculator

Understanding the Universal Gas Law

The equation \(pV = nRT\) relates gas properties:

• \(p\) = Pressure (kPa)
• \(V\) = Volume (L)
• \(n\) = Amount of substance (moles)
• \(R\) = Gas constant = 8.314 J·K⁻¹·mol⁻¹
• \(T\) = Temperature (Kelvin)

Example: For 100 kPa, 2.5 L, and 300 K:
\[n = \frac{(100 × 2.5)}{(8.314 × 300)} ≈ 0.100 \text{ moles}\]
