Suppose an ice cube weighing 44.7 g at a temperature of -4 degree celcius is placed in 550 grams of water at a temperature of 23 degrees celcius. Calculate the temp in degree celcius after thermoequillibrium is reached, assume no heat lost to the surroundings. The enthalpy of fusion of ice is molar heat = 6.007 kJ/mol, and the molar heat capacities of ice and water are 38 and 75 J/mol K respectively.
