1.) How much heat (in joules) is used to heat a 90.93 gram sample of iron from 6.34 degrees Celcius to 100.00 degrees Celcius if the specific heat of Fe is 0.450 J/g°C?

2.) 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 24.01 °C. You add ice to cool it. If the heat of fusion of ice is 6.020 kJ/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 4.06 °C? The specific heat of the "tea" is 4.184 J/g°C.
