An alloy is a solid solution between two metals. A 15.0 grams nugget of an alloy made from gold and copper with unknown composition is heated to 100.00 oC, similar to your experiment, and is dropped into a coffee cup calorimeter containing 25.0 ml of water. The initial temperature of water was 22.80 oC and the final temperature was 24.74 oC. Identify the mass percent of gold in the nugget if Cs, Au = 0.128 J/g oC, Cs, Cu = 0.385 J/g oC, and Cs, water = 4.18 J/g oC
