You say "I am not real sure exactly how to use it [the formula for latent heat of fusion] to find the average of some data." What exactly are you trying to find? Heat of fusion has nothing to do with "finding an average".
Well I just need to find the latent heat of all 3 of them, and then just average them all together. I thought I plugged everything in right, but when I tried to submit my answer it said that it was wrong. I just need to know where to plug everything in at.
Or maybe, another website I could go to that would help me with this. I have tried some, but they didn't work for me.
Okay, so you really have two problems: first use "Mw*Cw*(Tw-T) = Mi*Ci*(T-Ti)+L*Mi" to find the Latent Head of Fusion in each of the three cases, then add those values and divide by 3.
Well i guess my real problem is what is the mass of water. I know the volume (4 cups). I don't know what Cw is. I think Tw is temp of water. I think T is the final Temperater. Mi is I assume Mass of the ice. Not sure what Ci is. Again I believe that Tis the final Temperature and Ti is the temp of the ice. L is the Latent heat and Mi is the mass of ice again. Is that correct?
