A pneumatic lift consists of a vertical cylinder with aradius of 10.0 cm. A movable piston slides within the cylinder atits upper end and supports a platform on which loads are placed. Anintake valve allows compressed air from a tank to enter the cylinder,and an exhaust valve allows air to be removed from the cylinder. Ineither case the rate of air transfer is sufficiently low that the temperaturein the cylinder remains constant. When neither valve is activated,the cylinder is airtight. The piston and platform together have a massof 50.0 kg, the temperature is 20.0 C, and the pressure outside thecylinder is 1.00 atm. How many more moles of air should be introduced so that the platform rises 2.00 m above its original height?

Question
A pneumatic lift consists of a vertical cylinder with a
radius of 10.0 cm. A movable piston slides within the cylinder at
its upper end and supports a platform on which loads are placed. An
intake valve allows compressed air from a tank to enter the cylinder,
and an exhaust valve allows air to be removed from the cylinder. In
either case the rate of air transfer is sufficiently low that the temperature
in the cylinder remains constant. When neither valve is activated,
the cylinder is airtight. The piston and platform together have a mass
of 50.0 kg, the temperature is 20.0 C, and the pressure outside the
cylinder is 1.00 atm. How many more moles of air should be introduced
so that the platform rises 2.00 m above its original height?
