$2-44$ A gas is contained in a vertical, frictionless piston$-$cylinder device. The piston has a mass of $3\mathrm{.}2$ kg and a cross$-$sectional area of $35c{m}^2.$ A compressed spring above the piston exerts a force of $150$ N on the piston. If the atmosphere pressure is $95$ kpa,deterrmine the pres
