10 gm of ice at- 10° C is mixed with 100 gm of water at 50° C contained in a calorimeter weighing 50gm. (Specific heat of water = cal, gm^(-1).°C^(-1), Latent heat of ice = 80 cal//gm,specific heat of ice =0.5 "cal/gm/°C" and specific heat of copper = 0.09 "cal/gm/"°C). The final temperature reached by the mixtures is
