Diatomic gases and their molar masses
WebFeb 2, 2024 · The equation of Graham's law is: rate 1 / rate 2 = √ (mass 2 / mass 1) rate 1 and rate 2 - Rates of effusion or diffusion of Gas 1 and 2, respectively; mass 1 and mass 2 - Molar masses of Gas 1 and 2, respectively. This formula can be rearranged to calculate any variables, i.e., the rate of any of the gases or their molar masses. WebDiatomic gases can rotate about two axes perpendicular to their atomic bond. Thus, C P for a diatomic gas also includes a rotational heat capacity contribution C rot = 2(½ R ) = …
