A gas is confined to a cylinder with a movable piston. A small weight is placed on the piston after which the system reaches equilibrium, shown above. If the weight of the piston and the additional small weight is F = 76.0 N and the piston has an area of A = 3.00 x 10-4 m2, what pressure is exerted on the piston by the gas?
