Calculate the temperature change if a 58.2g sample of Pb absorbed the same amount of heat? Now I dont want the answer cause I want to work it out myself I just need to know how to set it up to get the right answer. I have atleast one example but no matter how many times I do it I never can get the same exact answer as the example...And its making me want to bang my head against the wall or taking this chem book and tossing it out the window..

Its thermochemistry if it helps oh and the previous question if it helps is how much heat must be absorbed by a 80.2g sample of water for the temperature to change from 24.2 Celsius to 66.2 Celsius.. I already have that answer just need an example for the last.

Heat = mass * Cp * DeltaT
you have mass, you are looking for DeltaT so,
DeltaT = Heat/mass/Cp.
You should have Cp and Heat in the text of the question.

uh elaborate more... but i think ur lookin for the heat gained by lead which is Q=massxCaloriexchange in temperature

Hi. I do not have your answer but congratulate you on asking for a way to work it out yourself.
