Latent heat

A 0.20 kg block of ice at $0\,^{\circ}\text{C}$ is dropped into $0.80\,\text{kg}$ of water at $20\,^{\circ}\text{C}$. Assume no heat loss to the surroundings. Take specific latent heat of fusion of ice as $3.3\times10^5\,\text{J/kg}$ and specific heat capacity of water as $4200\,\text{J/(kg K)}$. What is the final temperature of the mixture?
