Need help with my lab report for specific heat of unknown metal
I need to Find the Specific Heat of Al! I know its Q= M x Cs x Change in Temp
I am getting a such a high number am just confused if its right.
Here is what I got in Lab:
Aluminum
Mass of Metal (Mm): 6.128g
Mass of water (Mw) : 25 mL
Temp of water in calorimeter: 23.6 C
Temp of metal in water-bath: 100 C
T Final: 28.4 C
PLS helppp.... i am stuck on this!
Homework Answers
Cmetal*6.128*(100-28.4) = Cwater*25*(28.4-23.6)
Cmetal = 1.00*25*4.8)/[6.128*71.6]
= 0.274 cal/(g*C)

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 = (qwater + (calorimeter). The specific heats are positive numbers. 2. Calculate the average specific heat for your metal sample. 3. Calculate the standard deviation of your average specific heat capacity. 4.

The specific heat capacity of an unknown metal is to be found using calorimetry. A 35.0g sample of the metal is placed into a boiling water bath at a temperature of 100.0ºC. In the calorimeter lies 101.1g of water at a temperature of 22.1ºC. After thorough heating of the metal, it is transferred to the calorimeter. The final temperature of the metal/water system is 22.9ºC. Calculate the specific heat capacity of the metal.
