Question
Map A 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 50.73 g and the change in temperature was 2.35 C. Calculate the heat change of the calorimeter contents Number given that its specific heat is 4.10 J (g °C). Calculate the heat change of the calorimeter, Number Calculate the heat change of the solution process Number Hint O Previous ® Give Up & View Solution Check Answer Next HExi H Due Dat Late sub Points P Grade C Descript Policies: You can You can give up You can until you You lose answer attemp O eTextb HelpExplanation / Answer
1)
heat change of the contents,
Q1 = m*C*delta T
= 50.73g * 4.10 J/goC * 2.35 oC
= 489 J
Answer: 489 J
2)
heat change of calorimeter,
Q2 = C*delta T
= 8.5 J/oC * 2.35 oC
= 20.0 J
Answer: 20.0 J
3)
heat change for the process,
Q = Q1 +Q2
= 489 J + 20 J
= 509 J
Answer: 509 J
