8/2018 05:00 PM 3/10 Print Calculator 1/24/2018 08:41 PM Periodic Table Gradebo on 8 of 10 Incorrect Mapdoo Sapling Learning A calorimeter was used to measure the heat change when an ionic compound dissolves in water. The final mass of the contents of the calorimeter was 50.89 g and the change in temperature was 2.99 °C. Calculate the heat change of the calorimeter contents,Number given that its specific heat is 4.13 J/g·). 432.7 Calculate the heat change of the calorimeter, given that its heat capacity is 8.3 JC. Number 17.8 Number Calculate the heat change of the solution process. 450.5 incorrect ch

Explanation / Answer

heat change of calorimeter contents = m*s*DT

                    = 50.89*4.13*2.99
  
                    = 628.42 joule
heat change of calorimeter = c*DT

                      = 8.3*2.99

               = 24.82 joule

calculate heat change of the solution process = 628.42+24.82 = 653.24 joule
