A 4.75 g sample of aluminum pellets (specific heat capacity = 0.89 J °C-1 g-1) and a 10.00 g sample of iron pellets (specific heat capacity = 0.45 J °C-1 g-1) are heated to 100.0°C. The mixture of hot iron and aluminum is then dropped into 96.0 g of water at 20.7°C. Calculate the final temperature of the metal and water mixture, assuming no heat loss to the surroundings.
when 50.0 gram of metal at 75.0 C is added to 100 grams of water at 15.0 C the temperature of the water rises to 18.3 C. Assume that no heat is lost to the surroundings. What is the specific heat of this metal
