In spreading liquid ammonia fertilizer, the charges for the amount of ammonia used are based on the time involved plus the pounds of ammonia injected into the soil. After the liquid has been spread, there is still some ammonia left in the source tank (120 ft3) but in the form of a gas. Suppose that your weight tally, which is obtained by difference, shows a net weight of 125 lb. of ammonia at 292 psig. Because the tank is sitting in the sun, the temperature in the tank is 125 oF. Your boss complains that his calculations show that the specific volume of the ammonia gas is 1.20 ft3/lb and that there are only 100 lb. of ammonia in the tank. Could he be correct?
