**katie**, Sunday, March 20, 2011 at 12:35ami need help setting this problem up. i don't understand which numbers go where

**DrBob222**, Sunday, March 20, 2011 at 1:02pmThere is no setting up. Just substitute the numbers into the equation.

q = your answer.

mass water = 56.4g in the problem.

specific heat water = look this up in your text or notes. It is 4.184 J/gram I think.

Tfinal = 33.4 from the problem.

Tinitial = 20.4 from the problem.

q will be in joules, the problem asks for kJ; therefore, divide the answer you get by 1000 to convert J to kJ.
