Chemistry HW calculating specific heat/ molar enthalpy?

[alicia s]

I need to find the specific heat of an unknow metal.
The sample size was 20.112grams, Initial temp of calorimeter was 21 degrees celcius, heated the metal with boiling water (100c), then put it in calorimeter, the max temp of caliorimeter was 28.5
Whats the specific heat of unknown metal?

Whats the specific heat of KnO3, mass of sample 10.131 grams (1mol) initial temp of calorimeter 22degree celcius (using 100ml of distilled water), after puttin in salt final temp was 14 degree, temp change of -8 ......
Mass of salt solution?
molar enthalpy of solvation??
Specific heat of salt solution??
