An unknown volume of water at 18.2 degrees Celsius is added to 26.4 mL of water at 35.0 degrees Celsius. If the final temperature is 23.5 degrees Celsius, what was the unknown volume??
now, I know the density according to volume, and this allows me to assume an m (in q=mc :delta:T) for the 26.4 mL is 26.4 grams. how do i solve for the unknown volume? i think i'm making this problem more difficult than it has to be. any help is greatly appreciated.
