heat absorbed by gold + heat lost b Fe = 0
[mass Au x specific heat Au x (Tfinal-Tintial)] + [mass Fe x specific heat Fe x (Tfinal-Tintial)] = 0
Tfinal is the only unknown.
[mass Au x specific heat Au x (Tfinal-Tintial)] + [mass Fe x specific heat Fe x (Tfinal-Tintial)] = 0
Tfinal is the only unknown.
