I know you want someone to answer this for you, but is it that difficult to do it on your own? Who will be there on the test to do it for you?
Please see previous questions and answers and do this one the same way.
q = mC∆T
q = 0.606 J
m = 261 mg = 0.261 g
C = ?
∆T = 19.5 - 2.8 = 16.7º
Solve for C and get your answer in J/gº (use 2 sig.figs. based on 2.8ºC)
C = q/(m)(∆T) = 0.606 J/(0.261g)(16.7º) ... just do the math

Hello, I don't appreciate you being rude to me. I am confused on this question and created an account to ask for help. I don't know why you are acting so rude when I'm clearly confused and in need of assistance. I'm not sure what you're asking when you say to "Please see previous questions and answers" - this is my first time on this website. I appreciate your guidance for working through the answers, but that was a horrible first impression to make on someone's first time here.10/06/20
