Dimethylsulfoxide $($DMSO$)$ is an important solvent in organic chemistry, and also has many medical uses since it can enhance the penetration of medicinal agents during topological treatments. What is the total entropy change when $1\mathrm{.}00$ mol of DMSO $(\backslash$Delta Hfus $=14\mathrm{.}37$ kJ mol$-1)$ freezes at its freezing point, $19\mathrm{.}0\backslash$deg C$,$ in a freezer compartment whose temperature is held at $-86\mathrm{.}00\backslash$deg C$?$
