How can we calculate the rate of effusion of nitrogen gas from a cylinder and How much time it will take??
Ans) rate of effusion=r=(volume of nitrogen gas effusing from the cylinder)/(time taken)
also since pressure and temperature are constant, volume is proprtional to no. of moles
so,r=(no. of moles of N2 effusing)/(time taken)
