Question

Change in Temperature (C)
Moles of Mg (Use your Periodic Table):
Mass of final contents of calorimeter:
Heat gained (J)*
Heat gained per mole (J/mole)

Average heat gained per mole (from the 3 trials):

*Heat gained = (change in temperature) (mass of final contents of calorimeter) (4.18 J/gC)

Answer 1

ok

Answer 2

wheres the data?

Answer 3

trial 1 trial 2 trial 3
