A 848-G Piece of Silver (S = 0

A 84.8-g piece of silver (s = 0.237 J/(g ∙ °C) ) ,initially at 268.0°C,is added to 128.4 g of a liquid,initially at 24.9°C,in an insulated container.The final temperature of the metal-liquid mixture at equilibrium is 39.6°C.What is the identity of the liquid? Neglect the heat capacity of the container.

A) methanol (s = 2.53 J/(g ∙ °C) )
B) ethanol (s = 2.43 J/(g ∙ °C) )
C) hexane (s = 2.27 J/(g ∙ °C) )
D) water (s = 4.18 J/(g ∙ °C) )
E) acetone (s = 2.15 J/(g ∙ °C) )
