A piece of ice (heat capacity = 2100 J kg–1 º C–1 and latent heat = 3.36 × 105 J kg–1) of mass m grams is at –
5ºC 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 gm of ice has melted. Assuming there is no other heat
exchange in the process, the value of m is
