since the soulutions are dilute, assume that all the solutions have the same density and specific heat capacity of water. the heat capacity of the calorimeter is insignificant.
The heat of fusion of ice(the heat associated with ice melting) is 6.0 kJ/mol. Find the temperature of the coffee after the ice melts.
What volume of ethylene glycol (C2H6O2), a nonelectrolyte, must be added to 12.7 L of water to produce an antifreeze solution with a freezing point of -34.6°C? (The density of ethylene glycol is 1.11 g/cm3, and the density of water is 1.00 g/cm3.)
According to the Second Law of Thermodynamics, any process during which the entropy of the system increases will be product-favored.
