I've got the specific heat of a metal for three trials.

t1= .186 j/gdegrees C
t2= .178 j/gdegrees C
t3=.128j/gdegrees C

the mean of the specific heat is .164 j/gdegrees C

we're supposed to find which metal it is from a "CRC" handbook. I've tried and can't find any metal with this specific heat. Help.

Are you sure the specific heat capacity of the book has the same units as the ones you are comparing?
