how to do part a, trial 1
Data Analysis Part A. 1. Calculate the specific heat for your metal for each trial. Remember that the heat lost by the metal is equal to the heat gained by the water in the calorimeter and by the calorimeter itself. This can be expressed as - metal (water + Jealorimeter). The specific heats are positive numbers. EXP 8 - Thermochemistry Trial 3 Trial Trial 2 Trial 3 Part C 2 40.408 g 109.536...

5. Calculate the approximate final temperature of water in a coffee cup calorimeter if 33.9K heat is added to 420.0 g of water initially at a temperature of 22.60 °C (the specific heat water is 4.184 J/g.K). 6. Determine the mass of a sample of water in a coffee cup calorimeter if the final temperature is 65.7 °C, the initial temperature is 22.3 °C, and 27.6 kJ of heat is added to the water specific heat of water is 4.184J/g•K).

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.
