Calculate the work, w, done on the surroundings when a gas expands from 15L to 35L against a constant external pressure of 1.5 atm.[1L=101J].© BrainMass Inc. brainmass.com October 9, 2019, 7:59 pm ad1c9bdddf
1. Use ideal gas law:
PV = nRT
Molecular weight of Chlorine = 35.5*2 = 71 (g/mol)
n = 100/71 = 1.41 ...
The solution examines Celsius and external pressure.
