A large cylinder of helium filled at of had a small orifice through which helium escaped into evacuated space at the rate of 6.4 moles/ hour. How long would it take for 10 mole of CO were confined of the same pressure -
2.1 hour
4.2 hour
5.6 hour
11.2 hour
It would take 4.2 hour for 10 mole of co to leak through a similar orifice of the co were confined of the same pressure.
