When a sample which is having 9.00 g of metal is heated to 100.0 C, and dropped into the 20.0 mLs of water at the 25.00 C, the final temperature is 28.9 C.
1. Determine the specific heat of the metal, assuming the perfect insulation and a calorimeter heat capacity of zero.
2. Calculate the atomic weight of the element and guess its identity.
