The Calorimeter Constant is either 22.1J/C or perhaps the specific heat of water can be used? I calculated the answers using both options and neither got me an answer close to the theoretical. This is the given data so I'm not sure why I can't get an answer similar.
Here it should be noticed that heat capacity of calorimeter is given not specefic heat is given. So we dont have to multiple the mass of calorimeter.

Calculating specific heat capacity A constant-pressure calorimeter is often used to find the specific heat capacity of a substance if it is not known. A known mass of the substance can be heated and added to water of known mass and initial temperature. Since the specific heat capacity of water is known ( C s,water =4.184J/(g⋅ ∘ C)) , the amount of heat transferred to the water can be calculated by measuring the final temperature of the mixture at thermal...
