A 70 piece of ice at 0 is added to a sample of water at 6. All of the ice melts and the temperature of the water decreases to 0. How many grams of water were in the sample?

You need units on the numbers. 70 what? 6 what? etc.

Oh my gosh, sorry.

It's a 70g piece of ice at 0 degrees celsius is added to a sample of water at 6 degrees celsius. All of the ice melts and the temp of the water decreases to 0 degrees Celsius.

After searching other posts, I think I found the formula.

Mass x Heat of fusion + [mass water x specific heat of water x (tfinal - t initial)]=0 Is this correct?

I need to solve for mass of water, I just can't seem to wrap my head around how to do that. This seems like a foreign language to me. Thanks for your help. I have been working on this problem for 4 days. :(
