During the summer after your first year at Carnegie Mellon, you are lucky enough to get a job making coffee at Starbucks, but you tell your parents and friends that you have secured a lucrative position as a 'java engineer.' An eccentric chemistry professor stops in every day and orders 250 ml of house coffee at precisely 95*C. He then adds enough milk at 4*C to drop the temperature of the coffee to 90*C. Calculate the amount of milk, in ml, the professor must add to reach this temperature. Show all of your work including equations and units. Assume coffee and milk have the same specific heat capacity of 4.186 J/g*C and density of 1.0 g/ml.
