Latent Heat?

How much heat (both calories and joules) is required to raise the temperature of 40 kg of ice at -12 degrees C to steam at 250 degrees C? ume sea level air pressure. Specific heat of water is c=1.0; specific heats of ice and steam are .5. Latent heat of fusion of ice is 80 calories/gram. Latent heat of vaporization of water is 540 calories/gram.
