A piece of ice (heat capacity = 2100 Jkg^-1 C^-1 and latent heat = 3.36 x 10^5 J kg) of mass m gram is at-5°C at atmospheric pressure. It is given 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 heat exchange in the process,Find the value of m.
