We have that The  moles of air are in the cylinder and the volume would this air occupy at 1.0 atm and room Temperature is

  • V=5651.997L
  • n=229.756

From the question we are told

  • A compressed air cylinder stands 100 cm tall
  • internal diameter 20.0 cm
  • At room temperature, the pressure is 180 atm

Generally the equation for the Volume of Cylinder  is mathematically given as

[tex]V=\pi r^2l\\\\V=\pi *{\frac{20}{2*100}}*1\\\\V=31.4L[/tex]

Therefore

The equation for the ideal gas  is mathematically given as

[tex]PV=nRT\\\\n=\frac{PV}{RT}\\\\n=\frac{180*31.4}{0.082*300}\\\\n=229.756[/tex]

Generally the equation for the ideal gas  is mathematically given as

[tex]PV=nRTWhere\\\\V=\frac{nRT}{P}\\\\V=229.756*0.082*300\\\\V=5651.997L[/tex]
