The Gas Mixture Calculator is a scientifically precise, interactive tool that computes **partial pressures**, **mole fractions**, and **total pressure** in ideal gas mixtures using **Dalton’s Law of Partial Pressures**. Built on peer-reviewed principles from thermodynamics and physical chemistry, this calculator delivers accurate results for up to 10 gases. Whether you're analyzing greenhouse gas emissions, designing biogas systems, or teaching gas laws, this tool ensures reliability and clarity. Explore sustainable gas management at Agri Care Hub.
What is a Gas Mixture?
A **gas mixture** is a combination of two or more gases in a container. Under ideal conditions, each gas behaves independently, and the total pressure is the sum of individual partial pressures. This behavior is governed by **Dalton’s Law**, which states:
Where Pᵢ = nᵢ × (R × T) / V. This calculator uses verified methods from Gas Mixture engineering literature.
Scientific Principles: Dalton’s & Amagat’s Laws
Dalton’s Law: Partial pressure of gas i:
Where xᵢ = nᵢ / ntotal (mole fraction).
Amagat’s Law: Total volume is the sum of partial volumes at constant T and P.
