In a coffee-cup calorimeter, 50.0 mL of 0.100 M AgNO3 and 50 mLof 0.100M HCL are mixed to yield the subsequent reaction: Ag+ + Cl-=> AgClThe two solutions were primarily at 22.6 C and the final temperature is 23.40 C. Compute the heat that accompanies this reaction in kJ/mol of AgCl formed. Presume that the combined solution has a mass of 100.0g as well as has a specific heat capacity of 4.18 J/C*g.
