Part A

Two substances, A and $B,$ initially at different

temperatures, come into contact and reach thermal

equilibrium. The mass of substance $A$ is $6\mathrm{.}04g$

and its initial temperature is $21\mathrm{.}0C.$ The mass of

substance $B$ is $25\mathrm{.}0g$ and its initial temperature is

$52\mathrm{.}3C.$ The final temperature of both

substances at thermal equilibrium is $46\mathrm{.}8C.$

If the specific heat capacity of substance $B$ is $1\mathrm{.}17J{g}^{-1}{C}^{-1},$ what is the specific heat capacity of substance $A?$
