One mole of H2S gas escapes from a container by effusion in 77seconds. How long would it take one mole of NH3 gas to escape from the same container

One mole of H_2S gas escapes from a container by effusion in 77 seconds. How long would it take one mole of NH_3 gas to escape from the same container? Convert a pressure of 0.0248 mm Hg to the equivalent pressure in pascals (Pa). Air in a closed cylinder is heated from 25 degree C to 36 degree C. If the initial pressure is 3.80 atm, what is the final pressure? A bubble of helium gas has a volume of 0.650 mL near the bottom of a large aquarium where the pressure is 1.54 atm and the temperature is 12 degree C. Determine the bubble's volume upon rising near the top where the pressure is 1.01 atm and 16 degree C. At what temperature Celsius will 19.4 g of molecular oxygen, O_2, exert a pressure of 1820 mm Hg in a 5.12 L cylinder?

A small hole develops in the container above If neon starts to escape at 5.27 times 10^21 molecules per minute, at what rate does nitrogen escape? If all of the argon has escaped at 28.6 minutes, how long does it take for all of the neon to escape? If the neon escapes at 5.27 times 10^21 molecules per minute and the unknown gas escapes at 3.31 times 10^21 molecules/minute. What is the molar mass of the unknown gas?
