Question

The entropy change associated with the expansion of one mole of an ideal gas from an initial volume ofVi to a final volume of Vf at constant temperature is given by the equation, S = R ln (Vf/Vi). What is the entropy change associated with the expansion of three moles of an ideal gas from an initial volume of Vi to a final volume of Vf at constant temperature?
A) S = R ln (Vf/Vi)
B) S = 3 mol R ln (Vf/Vi)
C) S = R ln (Vf 23/Vi)
D) S = R ln (Vf 3!/Vi)
