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).

Explanation / 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
