Question

What is the minimum amount of ice (at 0 degress C) that must be added to 250mL of water at 23 degrees C in order to cool it to 0 degrees celsius? (Density of water= .98 g/cm^3; heat of fusion= 333J/g; heat capacity of water= 4.184J/g C; and heat capacity of ice= 1.86 J/g C)
heat gained by ice + heat lost by water = 0
(mass ice x heat fusion) + [mass water x specific heat water x (Tfinal-Tinitial)]
