1. The problem statement, all variables and given/known data What is the mass of a piece of nickel metal if it is heated to 100.0°C and placed into 250.0 grams of water at 21.52°C in a calorimeter with a heat capacity of 95.3J/K and the temperature stabilizes at 25.82°C? 2. Relevant equations -qnickel=+qwater 3. The attempt at a solution Well this problem is on our review for thermochemistry, but non of the examples we have done or seen (even in the book) really go this far. Here is my first attempt. -(cnickel X massnickel XΔTnickel)=cwater X masswater X ΔTwater Plugging in the knowns I get : Mass of nickel=(4.184J/g*K X 250.0g X 4.3K)/(0.444J/g*K X 74.18K)=136.6g of nickel I got the specific heat for water through memorization and the specific heat for nickel through a periodic table. Was able to solve it, but for some reason it doesn't feel right. Can't find an example of something similar anywhere. Am I on the right track at least?
