A 61.93 gram sample of iron (with a specific heat of 0.450 J/g °C) is heated to 100.0 °C. It is then transferred to a coffee cup calorimeter containing 40.6 g of water (specific heat of 4.184 J/ g °C) initally at 20.63 °C. If the final temperature of the system is 23.59, what was the heat absorbed (q) of the calorimeter? (total heat absorbed by the water and calorimeter = heat released by the iron)

A 61.18 gram sample of iron (with a heat capacity of 0.450 J/g℃) is heated to 100.00。It is then transferred to a coffee cup calorimeter containing 52.33 g of water (specific heat of 4.184 J/ g℃) initially at 20.67 ℃. If the final temperature of the system is 28.40, what was the heat gained by the calorimeter? If the calorimeter had a mass of 27.88 g, what is the heat capacity of the calorimeter? J absorbed by the calorimeter
