Effusion

Q. Effusion is a process in which a gas escapes from a container through a small opening into a vacuum, In a pair of experiments, a sample of tetrafluoroethylene, C2F4, effuses at a rate of 4.6 x 10^-6 mol/h and an unknown gas effuses at a rate of 4.0 x 10^-6 mol/h. Identify the unknown gas. (The molar mass of each gas is given.) a. N2 28.01 g/mol b. CO2 44.01 g/mol c. SF6 146.06 g/mol d. Xe 131.29 g/mol e. CHCl3 119.38 g/mol
