How do i describe how to determine the specific heat of a sample of a solid substance

You describ that the heat is getting trapped and not released

Use calorimetric to determine the specific heat and measure the mass of a sample

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
