You are testing some novel fuel mixtures for potential use in automobiles. Your testing apparatus is a 2.54-cm inner diameter cylinder fitted with a piston, designed to mimic a cylinder found in a car engine. A fuel/air mixture is ignited while a force of 269.0 N is applied to the piston. If there are 0.280 mol of gas after combustion at 330.0°C, and the atmospheric pressure is 1.01325 × 105 Pa,1) What is the pressure of gas inside the cylinder at these initial conditions? Assume the combustion products behave ideally.2) What is the volume of gas in the cylinder?
