That's the problem, I don't know. It seems like it can't be part of the equation for the metal's shc because it used the waters shc, so I can't figure it out.
The farthest I got was double thermal energy equals mass times specific heat capacity times change in temperature (115+34)
2Eth=(mc149)
To
Eth=mc74.5
I'm not sure where to go from here. It seems like I don't have enough information.
