The label on a tank of gas of unknown origin had been lost. To determine its identity (molecular weight) a certain volume of it took 76.32 seconds to effuse through a porous partition. Under identical conditions HCN effused through the hole in 59.75 seconds. What is the molar mass of the unknown gas? Remember that effusion rate and time are inversely proportional to each other.
