Air is pumped into the tubes of cycle rickshaw at a pressure of 2 atm. The volume of each tube at this pressure is `0,002m^(3)` One of the tube get punctured and the volume of tube reduces to `0.0005m^(3)` How many mole of air have leaked out? Assume that many mole of air have leaked out? Assume that temperature remains constant at `300K` and air behaves as ideal gas .

Answer

`0.142`
