[masss Al x specific heat Al x (Tfinal-Tinitial)] + [mass water x specific heat water x (Tfinal-Tinitial)] = 0
Solve for Tfinal.
Solve for Tfinal.

(3.9)*(0.9025J)*(Tfinal-99.3)+(10)*(4.184J)*(Tfinal-22.6)=0
(3.51975J)*(Tfinal-99.3)+(41.84J)*(Tfinal-22.6)=0
45.35975JTfinal-1295.095175=0
1295.095175/45.35975=28.6 degrees celsius
(3.51975J)*(Tfinal-99.3)+(41.84J)*(Tfinal-22.6)=0
