a 225.0g sample of an unknown, silver, pure metal was heated to 95.5 degrees Celsius and then put into 150.50g of water at 22.5 degree Celsius. the water was heated by the hot metal to a temp. of 31.4 degree Celsius. what is the specific heat of the metal and what is the metal?

heat lost by metal + heat gained by H2O = 0

[mass metal x specific heat metal x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Substitute and solve for specific heat metal, then look in specific heat tables and identify the metal with that specific heat .
