[mass alloy x specific heat alloy x (Tfinal-Tinitial)] + [(calorimeter constant x (Tfinal-Tinitial)] = 0
(30.5)(X)(10.8)+(?)(10.8)=0
What number goes in the calorimeter constant ?
9.2 J/K = heat capacity of the coffee cup.
It's still not giving me the right answer. I'm pulling in the numbers, and doing the equation right. But, it keeps telling me, I am wrong.
I didn't include the water and should have done so.
(mass water x specific heat water x (Tfinal-Tinitial)) + (mass alloy x specific heat alloy x (Tfinal-Tinitial)) + Ccal(Tfinal-Tinitial) = 0
so, what is the t final- t initial for ccal?
