A student in a physics lab course has the task of measuring the pressure of a gas as a function of volume. Helium gas is placed in a cylinder that is fitted with a piston. By pushing the piston down, the student reduces the volume of the gas by a known amount and then measures the resulting gauge pressure (pressure relative to 1 atm). The measurements are made at room temperature (20°C). The resulting data are shown in the table. Volume (L) Gauge Pressure (atm) 0.2 112 0.4 5.03 0.6 3.06 0.8 2.03 1.0 1.42 Make a linearized plot of the pressure-versus-volume data. Determine the number of moles of helium in the cylinder by using a “best fit” to the data.
