A 40.0g sample of an unknow, yellowish-brown, pure metal was heated to 62degrees Celcius and put into a coffee cup calorimeter containing 85.0g of watera at 19.2 degrees Celcius. The water was heated by the hot metal to a temperature of 21.0 degrees Celcius. What is the specific heat of the metal? Is it possible that the metl is gold?

[mass M x sp.h.M x (Tfinal-Tinitial)] + [mass H2O x specific heat water x (Tfinal-Tinitial)] = 0
solve for sp.h. M
I don't think it's Au.
