A plass $(100$ mL$)$ of water at $80C$ is left in a room at $20C$ and the water is expected to cool down to thermal equilibrium. Meanwhile, how many J$/$K would be entropy change in the universe $?$

Assume that the volume of the room in too large and therefore the room temperature does not change.Assume that the pressure in the room is unchanged and the room is isolated from the enviroment. $($ heat capacity of water at constant pressure Cp$=75$ J$/$mol$.$K; densitynof water $=1$ g$/$ cm$3$
