Question

A 5.00-g sample of aluminum pellets (specific heat capacity = 0.89 J/°C · g) and a 10.00-g sample of iron pellets (specific heat capacity = 0.45 J/°C · g) are heated to 100.0°C. The mixture of hot iron and aluminum is then dropped into 92.5 g of water at 21.9°C. Calculate the final temperature of the metal and water mixture, assuming no heat loss to the surroundings.
