A cylinder contains ethylene (C2H4) at 200 psig. The cylinder as well as gas weight is 222 lb. The supplier refills the cylinder with ethylene until the pressure reaches 1000 psig, at which the cylinder and gas weigh 250 lb. The temperature is presumed to be constant at 25 C. Compute the charge to be made for the ethylene if the ethylene is sold at $0.41/ pound. Calculate the weight of empty cylinder and its volume. Calculate the volume of the cylinder.
