q = mass water x specific heat water x (Tfinal-Tinitial)
i need help setting this problem up. i don't understand which numbers go where
There 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.
