Question

21.90 kJ/g x 0.1182 g = ?q = energy obtained by combusting salicylic acid.

Then calculate the heat capacity of the calorimeter. That is
q from above = C/degree c x 2.84 and solve for C, the heat capacity of the calorimeter.

q = heat capacity x delta T
q = Cfrom above x 3.50
Solve for q and that is q/0.2086g and that gives you q/gram of the unknow

Answer 1

I see my response to one of your earlier question but no question
