The equation you will use is q = mCΔT

q = heat = 23.8 J

m = mass = ?

C = heat capacity =?

ΔT = change in temperature = ?

So as you can see we have 2 unknowns. We need to know the mass of the unknown metal.

The question does not give you the mass. I thought you could just use the heat capacity formula which is c=q/delta T? It would be 23.8J/15.4C= 1.55J. Is that correct?11/24/19
