Concept explainers
Interpretation:
Molar mass and molecular formula of compound with empirical formula
Concept Introduction:
Subscript of empirical formula is multiplied by value of
Effusion is explained as movement of the gas molecule through small hole.
Diffusion can be explained as when one gas molecule mix with another gas molecule by random motion.
Graham’s law of effusion gives relation of rate of effusion with molar mass. Rate of effusion and square root of molar mass are inversely related. The mathematical expression is as follows:
