Tabulating the z factors and ideal volumes at each pressure value and find out the specific gas gravity of the gas.
A cylinder is fitted with a leak proof piston and calibrated so that the volume within cylinder can be read from a scale for any position of the piston. The cylinder is immersed in a constanttemperature bath maintained at 160 F. About 45,000 cm^{3} of the gas, measured at 14.7 psia and 60 F is charged into the cylinder. The volume is decreased in the steps indicated below, and the corresponding pressures are read with a deadweight tester after temperature equilibrium is reached.
1. Compute and place in tabular form the z factors and the ideal volumes that the initial 45,000 cm^{3} occupies at 160 F and at each pressure.
2. Compute the specific gas gravity of the gas.
