The ratio of gas effusion is 2.697.
What is rate of effusion?
Effusion: When a gas is contained in a container at a pressure higher than that of the surrounding atmosphere, the gas will escape through a small hole that is opened in the container until the pressures inside and outside are equal. Effusion is the name given to this process.
The rates of diffusion of various gases are inversely correlated to the square roots of their molecular masses or densities, according to Graham's law of diffusion, which states "under the same conditions of temperature and pressure."
The number of molecules that diffuse through the hole in one unit of time is the rate of effusion. The effusion rate is inversely related to the molecular weight when pressure and temperature are constant.
Inversely related to √M is the effusion rate.
Be gas's molar mass is equal to 9.01 u
Mg's molar mass is equal to 24.30 g/mole.
Be/Mg ratio equals 24.30/9.01, or 2.6
