One mole of an ideal gas is expanded from a volume of 3.00 L to a volume of 10.38 L against a constant external pressure of 1.08 atm. Calculate the work. (1 L•atm = 101.3 J)

Question

Quizplus · Accepted Answer

The work done by the gas during expansion is calculated using the formula: work = -PΔV. Here, P = 1.08 atm and ΔV = (10.38 - 3.00) L = 7.38 L. Thus, work = -1.08 atm * 7.38 L = -7.9704 L•atm. Converting to joules: -7.9704 L•atm * 101.3 J/L•atm = -807.2 J, which is approximately -8.07 × 10² J.
