You order a 16 oz glass of tea ( where the mass of water is 474 grams) from a local restaurant . The tea is freshly brewed and has an initial temperature of 29,44 C. You add ice to cool it. If the heat of fusion of is 6.020^ 2 kl mol and each ice cube contains exactly 1 mol of water (assume the ice does not add anymore volume), how many ice cubes are necessary to cool the tea to 1.58 °C? The specific heat of the "tea " is 4.184^ 1 / g^ C
