A 50.0 g piece of iron metal is heated to 200. oC. Then, the iron is placed into a water bath which is at 25.0oC. Eventually, both the iron and the water reach a temperature of 30.0oC. Determine the mass of water used in the experiment. (Specific heat for water is 4.184 J/g . oC ; the specific heat for iron is 0.449 J/g . C )
