A 610-g quantity of an ideal gas undergoes a reversible isothermal compression at a temperature of 330K.  The compression reduces the volume of the gas from 0.40 m3 initially, to 0.21m3 finally. The molecular mass of the gas is 33.0 g/mol, and the ideal gas constant is R = 8.314 J/(mol ∙ K). What is the entropy change for the gas for this process? [entropy]
