Determination of molar mass using the ideal gas law. P3010401
You can get the concept of: Molar mass, properties of gases, ideal and real gases, equations of state of ideal gases.
Principle: All gases can be considered a first approximation, as satisfying the equation idealnog gas, which relates the pressure p, volume V, temperature T and the amount of substance n of the gas. If the volume occupied by a known mass of gas, measured at a given temperature and pressure, then the equation can be used to estimate the molar mass of gas. In this experiment, determined by the molar mass of helium, nitrogen, carbon dioxide and methane.
