The specific heat of iron is 0.449 J/(g . oC) and the specific heat of water is 4.184 J/(g . oC). A piece of iron was heated to 98.1oC and dropped into a constant pressure calorimeter containing 262 grams of water at 34.9oC. The final temperature of the water and iron was 48.4oC. Assuming that the calorimeter itself absorbs a negligible amount of heat, what was the mass, in g, of the piece of iron? A) 7.64 g B) 159 g C) 1.51 x 10-03 g D) 683 g E) 6.31 x 10-03 g F) 663 g G) 714 g
