A 14.7-g sample of iron pellets (specific heat capacity 0.460 J/°C.g) and a 13.4-g sample of gold pellets (specific heat capacity 0.126 J/ °C g) were heated to 195°C. The mixture of hot metal is dropped into 125 g of ethylene glycol (specific heat capacity 2.43 J/°C g) at 21.3°C. Assuming no heat loss to the surroundings, calculate the final temperature of the metal and ethylene glycol mixture.
