The entropy of vaporization of benzene is \( 85 \mathrm{JK}^{-1} \)
P \( \mathrm{mol}^{-1} \). When \( 117 \mathrm{~g} \) benzene vaporizes at its normal boiling point, the entropy change of surrounding is :
W
(1) \( -85 \mathrm{~J} / \mathrm{K} \)
(2) \( -85 \times 1.5 \mathrm{~J} / \mathrm{K} \)
(3) \( 85 \times 1.55 \mathrm{~J} / \mathrm{K} \)
(4) None of these
