An empty coffee-cup calorimeter weighs 10 grams. It is filled with water, whose temperature is 31 degrees Celsius, and is weighed again. The weighing scale displayed 55 grams.


A metal sample is heated to 90 degrees Celsius and then placed into the coffee-cup calorimeter. The cover, with a thermometer, is quickly put on top of the calorimeter. The temperature reading on the thermometer stabilized at 33 degrees Celsius. The mass of the metal is 6.45 grams. Use 4.184 J/g∙0C for the specific heat of water.


What is the specific heat in J/g∙0C of the metal sample?
