Ideal Gas State Equation Calculator

Calculate the pressure of an ideal gas using the equation: $$ P = \frac{nRT}{V} $$

* Enter the number of moles (mol), temperature (K), and volume (m³). The gas constant $ R $ is taken as 8.3144621 J/(mol·K).

Step 1: Enter Parameters

Number of Moles, $ n $ (mol):

e.g., 1 mol

Temperature, $ T $ (K):

e.g., 298 K (25°C)

Volume, $ V $ (m³):

e.g., 0.0224 m³ (approx. at STP for 1 mol)
