3.00 moles of an ideal monoatomic gas are compressed isothermally at a temperature of 300 K from a pressure of 0.320 bar to a pressure of 1.43 bar. What is the change in entropy of the gas?
a. -37.3 J/K
b. 0.868 J/K
c. 0.371 J/K
d. -0.371 J/K
e. To answer this question, we need to know how the enthalpy of the gas changes with pressure.
