The Enthalpy and Entropy of Vaporization of Ammonia at Its $\circ$

The enthalpy and entropy of vaporization of ammonia at its normal boiling point,-33.34 ^$\circ$ C,are 23.35 kJ/mol and 97.4 J/mol . K,respectively.What is the entropy change of the universe when one mole of liquid ammonia vaporizes in a large room maintained at 34.0 ^$\circ$ C? Assume the final temperature of the ammonia gas is -33.34 ^$\circ$ C.

A) +21.4 J/K
B) -76.0 J/K
C) +74.1 J/K
D) -21.4 J/K
E) +76.0 J/K
