A piece of iron, which has a specific heat capacity of 0.452 J.g-¹°C-1, with a mass of 54.3218 g is heated in a water bath until it reaches a temperature of 98.2 °C. The iron is then transferred into a coffee-cup calorimeter made of nested Styrofoam cups that contains 68.5314 g of water initially at 22.1 °C. The final temperature of the entire system is 27.5 °C. Based on this information, determine the calorimeter constant Ccal for this particular calorimeter in J.˚C-¹. Recall that the specific heat capacity of water is 4.184 J.g¹.°C-¹.

Transcribed Image Text:A piece of iron, which has a specific heat capacity of 0.452 J.g¹. C-¹, with a mass of
54.3218 g is heated in a water bath until it reaches a temperature of 98.2 °C. The
iron is then transferred into a coffee-cup calorimeter made of nested Styrofoam cups
that contains 68.5314 g of water initially at 22.1 °C. The final temperature of the
entire system is 27.5 °C. Based on this information, determine the calorimeter
constant Ccal for this particular calorimeter in J.˚C-¹. Recall that the specific heat capacity
of water is 4.184 J·g¯¹.°C-¹.
