How many milliliters of water at 23 C with a density of 1.00 g/mL must be mixed with 180 mL (about 6 oz) of coffee at 95 C so that the resulting combination will have a temperature of 60 C? Assume that coffee and water have the same density and the same specific heat (4.184 J/g C). * O 17 170 10.7 107 A 45-g aluminum spoon (specific heat 0.88 Jlg C) at 24 C is placed in 180 mL (180 g) of coffee at 85 C and the temperature of the two become equal. What is the final temperature when the two become equal? Assume that coffee has the same specific heat as water. * 76.38 88.45 84.67 81.95 K
