A piece of ice (heat capacity #= 2100J kg^(-1 @)C ^-1# and latent heat #= 3.36 xx 10^5 J kg^-1# ) of mass #m# gram is at #-5^@C# at atmospheric pressure. It isgiven #420 J# of heat so that the ice starts melting. Finally when the ice-water mixture is in equilibrium, it is found that #1 g# of ice has melted. Assuming there is no other exchange in the process, the value of #m# is?
