Calculate the heat capacity of the unknown metal T-mu (Ds)lo.1on) 5.144 5.J44 J/C 61. Based on your calculated specific heat capacity, what unknown metal is the washer most likely made of? 62. What is the percent error between your calculated specific heat capacity and the specific heat capacity of the metal you identified above reported in the literature? What are some of the possible sources of error in this experiment. If the metal is not pure, skip the %calculation part. % error

can someone check my math for #59 and #60? i feel like my answers are incorrect.

Answer 1

If T_f = 26.8⁰C , then your  calculation is correct.
