Question
A coffee-cup calorimeter contains 50 ml of water with an initial temperature of 24.8°C. An unknown sample with a mass of
1.972 grams was placed inside making the water temperature rise up to 25.5°C. The initial temperature of the metal was
98.3°C. (Water: density = 1g/mL; specific heat = 4.184 J/g-°C).
1. How much heat (in Joules) was absorbed by the water in the calorimeter?
(round off final answer to 2
decimal places)
146.30
