What Is the Heat Capacity of the Alloy in This Experiment?

[nikan_ange]

Homework Statement

to determine the specific heat of a metal alloy, a 0.150 kg of the substance is heated to 400 degrees C ad then placed in a 0.20 kg aluminum calorimeter containing 0.40 kg of water. if a 14 g of ice is placed on it and the mixture reached the temperature of 30.5 degrees C, what is the heat capacity of the alloy?

The Attempt at a Solution

the hint given by our teacher is to get the heat capacity and heat vaporization of steam

pls help me with this prob...we were only taught for a very short time about this..

What is the definition of "heat capacity"? In particular looking at the units, Joules per kilogram per kelvin, should help you see what you need to do. One thing you will need to know, that is not given here, is original temperature of the calorimeter and water. I don't see any need for "heat of vaporization" since the water does not appear to vaporize here but you will want to look up the specific heat of aluminum and water and the heat of melting of water.
