Hello, can you please kindly help me with the chemistry? Thanks a lot!

Q.1 : -E water = E metal (my teacher said - E of water has to mentioned), my question is Cp of the metal will be - ? or we do not need to mention?

The temperature of a metal weighing 35g is 92 When this metal is introduced into 60g of water at 25, the temperature of the water increases to 30.7 (final temperature of the water + metal mixture). Calculate the specific heat capacity Cp of the metal, knowing that that of water is 4.181 J
