5 gm of ice at -10^@C are mixed with 20 ...

5 gm of ice at `-10^@C` are mixed with 20 gm of water at `39^@C`. Will whole of the ice melt? If so, what is the final temperature of the mixture? Specific heat capacity of ice = `0.5 cal gm^-1 "^@C^-1` and latent heat of fusion of ice = `80 cal gm^-1`, specific heat capacity of water = `1cal gm^-1 "^@C^-1`.
