Question

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

Answer 1

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. 

Answer 2

Answer:

54.4 seconds

Explanation:

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.
