A sample of

0.50\,\text{mol}

of an ideal monatomic gas expands isothermally and reversibly at

300\,\text{K}

from an initial volume of

2.0\,\text{L}

to a final volume of

6.0\,\text{L}

. Which of the following is closest to the change in entropy

\Delta S

of the gas? (a)

0\,\text{J/K}

(b)

9.1\,\text{J/K}

(c)

4.6\,\text{J/K}

(d)

2.9\,\text{J/K}
