Chemistry
How much heat did the water lose in going from 45 to 19.5 degrees? Mass x specific heat water x (Tfinal-Tinitial). How much heat did the ice gain? mass ice x heat fusion. heat lost + heat gain = 0. The only unknown is mass ice.

When ice melts, it absorbs 0.33 kJ per gram. How much ice is required to cool a 24.0 fluid ounce drink from 75F to 35F, if the heat capacity of the drink is 4.18 J/gC? (Assume that the heat transfer is 100% efficient.)

hang on I dont know why it keeps doing that. how much heat would be required to warm Earths ocean by 1.0 degrees C assuming that the volume is 137*10^7 km ^3 and the density of sea water is 1.03 g/cm 3. also assume that the heat capacity of seawater is the same as that of water
