An oxygen cylinder of volume 30 litre ha...

An oxygen cylinder of volume 30 litre has an initial gauge pressure of 15 atm and a temperature of `20^(@)C`. After some oxygen is withdrawn from the cylinder, the gauge pressure drops to 11 atm and its temperature drop to `17^(@)C`. Estimate the mass ( inkg) of oxygen taken out of the cylinder, `R=8.3J"mol"^(-1)K^(-1)`, molecule weight of oxygen =32.

AI Generated Solution

To solve the problem, we will use the Ideal Gas Law, which is given by the equation: \[ PV = nRT \] Where: - \( P \) = pressure (in Pascals) - \( V \) = volume (in cubic meters) - \( n \) = number of moles ...
