Answer:
6.94 × 10⁴ J
Explanation:
We can calculate the work (W) associated with the compression of a gas at constant pressure using the following expression:
W = -P . ΔV
where,
P is the external pressure
ΔV is the change in the volume
Knowing that 1 atm.L = 101.325 J, the work of compression is:
[tex]W=-P\times \Delta V=-16.7atm\times(80.0L-121.0L)\times\frac{101.325J}{1atm.L} =6.94\times10^{4} J[/tex]
The positive sign of the work means that the surroundings do work on the system.
