An chemistry professor stops in every day and orders 250 ml of Sumatran coffee at precisely 95°C. He then adds enough milk at 10°C to drop the temperature of the coffee to 90°C. a) Calculate the amount of milk (in ml) the professor must add to reach this temperature. (Assume coffee and milk have the same specific heat capacity: 4.186 J/g °C. Assume that they also have the same density: 1.0 g/ml.)
