A Piece of a Newly Synthesized Material of Mass 12 $\circ$

A piece of a newly synthesized material of mass 12.0 g at 88.0 ^$\circ$ C is placed in a calorimeter containing 100.0 g of water at 20.0 ^$\circ$ C.If the final temperature of the system is 24.0 ^$\circ$ C,what is the specific heat capacity of this material?

A) 10.2 J.g^-1.( ^$\circ$ C) ^-1
B) 1.58 J.g^-1.( ^$\circ$ C) ^-1
C) 2.18 J.g^-1.( ^$\circ$ C) ^-1
D) 9.50 J.g^-1.( ^$\circ$ C) ^-1
E) 0.54 J.g^-1.( ^$\circ$ C) ^-1
