If 100. g of water at 55C is combined with 300. g of water at 15C, what is the final temperature of the 400. g of water?

Hint: 25% of the 400. g starts at 55C while 75% starts at 15C.

Hey there! So the heat released by the hotter water will just be the same as the heat absorbed by the colder one. Their final temperatures should also be the same. With that said, an equation can be made such as shown below:

Cp can just be canceled since they are just both water.

I hope this helps!
