Suppose that there are two very large reservoirs of water, one at a temperature of 95.0 °C, and one at a temperature of 11.0 ℃. These reservoirs are brought into thermal contact long enough for 36330 J of heat to flow from the hot water to the cold water. Assume that the reservoirs are large enough so that the temperatures do not change significantly What is the total change in entropy resulting from this heat exchange between the hot water...

i got this question wrong. the book previously said that the
units of entropy are J/(mol*K). you can get mol with the grams that
they gave, so why not use it?
Example: If, in a reversible process, 6.66 x 10 J of heat is used to change a 200 g block of ice to water at a temperature of 273 K, what is the change in the entropy of the system? (Note: The heat of fusion of ice = 333...
