(A) How much work, in joules, is involved when 0.225 mol N₂ at a constant temperature of 23 °C is allowed to expand by 1.50 L in volume against an external pressure of 0.750 atm?

(B) How much work is done, in joules, when an external pressure of 2.50 atm is applied, at a constant temperature of 20.0 °C, to 50.0 g N₂(g) in a 75.0 L cylinder? The cylinder is like that shown in Figure 7-8.
