You need to know the specific heat of the Ag metal.
You need to know the specific heat of the glass rod.
You need to know the specific heat of water.
[mass Ag x specific heat Ag x (Tfinal-Tinital)] + [mass of glass rod x specific heat glass rod x (Tfinal-Tintial)] + [mass water x specific heat water x (Tfinal-Tinitial)] = 0
Substitute the numbers and solve for Tfinal. Post your work if you get stuck.
A student conducted a calorimetry experiment where 76.0 g of silver metal at 75.0°C was dropped into a Styrofoam cup
calorimeter containing 125 g of water at 15.0°C. Also in the cup was a 35.0 g glass stirring rod, also at 15.0°C. Assuming no heat is transferred between the system & the Styrofoam cup, what was the final temperature of the system?
