3. A vertical cylinder of cross-sectional area A is fitted with a tight-fitting, frictionless
piston in the figure below. The piston is not restricted in its motion in any way and is
supported by the gas at pressure p below it. Atmospheric pressure is po. Suppose n
moles of an ideal gas are in the cylinder at a temperature of T, what is the correct
expression for the mass m of the piston? (Use the following as necessary: A, g, n, po,
