This experiment was conducted at a temperature of 298 K. If R = 0.082 atm L/mole K, use the numerical value of the slope of this line to determine the number of moles of gas present in the container during the experiment.

Use the equation of the line to extrapolate the pressure on the gas when the volume was 20 liters.
