Asked by Emmanuel
A student heats 64.05 grams of nickel to 97.80 °C and then drops it into a cup containing 81.11 grams of water at 21.79 °C. She measures the final temperature to be 27.84 °C.
The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.50 J/°C.
Assuming that no heat is lost to the surroundings calculate the specific heat of nickel.

[mass Ni x specific heat Ni x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] + Ccal x (Tfinal-Tinitial) = 0
specific heat Ni is the only unknown. Substitute and solve for that. Post your work if you get stuck.
