# How to use specific heats and temperature change in a system to calculate mass?

In a system where multiple liquids and solids are mixed together with different specific heats at different initial temperatures, reaching an equilibrium temperature, how do all of these things relate to the masses? How could I use all the information given of the other objects to find the mass of one object in the system?

I know Q=cm*deltaT is the formula that relates heat added to the mass, specific heat and temperature change, where normally I could just take m=Q/cdT (I think) and find the mass easily but I am just not sure how to relate this to an entire system where many things are working together. Any pointers would be appreciated, thanks.

Can you give a sample problem of the type you're considering? Then we can show you how to work through that problem. – John Rennie Apr 13 '14 at 8:23
