2 kg of ice at \[\text{ }20{}^\circ C\] is mixed with 5kg of water at \[20{}^\circ C\] in an insulating vessel having a negligible heat capacity. Calculate the final mass of water remaining in the container. It is given that the specific heats of water and ice are \[1\text{ }kcal/kg\text{ }/{}^\circ C\] and \[0.5\text{ }kcal/kg/{}^\circ C\] while the latent heat of fusion of ice is 80 kcal/kg
