I'm having a problem in solving specific heat equations. I get the basic concept and know the formula, but in doing the sample problems, I can't seem to get them right. I have a lab assignment where I need to find the specific heat capacity for Fe. I have all the required information filled in on the observation sheet.

Here's the problem:

Mass of Fe: 100gm

Volume of water in calorimeter:

Mass of water in calorimeter:

Initial Temp:20 degrees C

Final Temp: 100 degrees C

Final Temp of both the metal and water: 100 degrees C

Determine the heat gained by the water (show your work)

Q water=

Q Fe=

2. Relevant equations

Q= C(specific heat) x Mass x change of temperature

3. The attempt at a solution

What I have done so far is

Mass= 100

C= 0.108

Tf= 100 C

TI=20 c

from there Q=100*0.108*80= 864 (I know somethings wrong with that answer)

I think it has to do with C, I tried finding the Specific heat of Iron online and came up with several different answers
