A quantity of water at 87 degrees C is cooled at a rate of 2844 MJ/h. After 40 minutes, the water has changed to ice, having a temperature of 243K. Calculate the mass of the water/ice.
I know 243K = -30 degrees C
I'm assuming I have to use my sensible and latent heat formulas but I would need heat energy in kJ.
