Large amounts of nitrogen gas are used in the manufacture of ammonia,
principally for use in fertilizers. Suppose 120.00 kg of N2(g) is stored in a 1100.0-L

metal cylinder at 280 °C.
(a) Calculate the pressure of the gas, assuming ideal-
gas behavior.
(b) By using the data in Table 5.4(material entitled”Gases”), calculate the
pressure of the gas according to the van der Waals equation.
(c) Under the conditions of this problem, which correction dominates, the one for
finite volume of gas molecules or the one for attractive interactions?
