One mole of h2s gas escapes from a container by effusion in 77 seconds how long would it take one mole of nh3 gas to escape from the same container

The molar masses of H2S and NH3 are 34 and 17 g/mol, respectively. The equation that would best represent the given is,

Rate A/Rate B = √ (molar mass B/molar mass A)

Substituting,

x/77 = √ (17 / 34)

x = 54.4

Thus, it will take 54.4 seconds for NH3 to travel through the container.
