A molecule takes 3.0 seconds to diffuse across a membrane. If the thickness of the membrane is doubled, then how long does it take the molecule to diffuse across the thicker membrane?

140cm^3 of nitrogen gas diffuses through a membrane in 70seconds. How long will it take 200cm^3 of carbon(iv)oxide gas to diffuse through the same membrane under the same conditions of temperature and pressure
