Use V₁/n₁ = V₂/n₂ — leave the value you want to calculate empty.
How it works: Avogadro’s law states that at constant temperature and pressure the volume of a gas is directly proportional to the number of moles (V ∝ n). We use the relation V₁/n₁ = V₂/n₂. Enter three known values and leave the unknown blank — press Calculate.

The Avogadro’s Law Calculator is a useful tool that helps determine the relationship between the volume and the number of moles of a gas at constant temperature and pressure. According to Avogadro’s law, the volume of a gas is directly proportional to the number of moles when temperature and pressure remain constant. This means that if the amount of gas increases, its volume also increases proportionally. The calculator applies the formula V₁/n₁ = V₂/n₂, allowing users to find the unknown value by entering any three known variables. It is commonly used in chemistry to understand gas behavior, perform lab calculations, and verify experimental results with ease.
