If can could you help with these questions.
If 50.0 g of H2O at 82.5oC and 50.0 g of H2O at 25.0°C are mixed in a styrofoam cup calorimeter at 25.0°C and the final temperature is 37.5°C, what is the calorimeter constant?
The calorimeter constant of a bomb calorimeter is 1786 J/°C. If the combustion of 3.738 g of a substance with a molar mass of 60.0 g/mole raised the temperature of 1500.0 g of water and the calorimeter from 20.0°C to 25.3°C, what is the molar heat of combustion of the substance (in kJ/mole)?
If 146.9 g of H2O at 93.0°C and 279 g of H2O at 23.0°C are mixed in a calorimeter (with an initial temperature of 23.0°C) and a calorimeter constant of 135.5 J/°C, what is the final temperature of the water and calorimeter? The specific heat of water is 4.184 J/g°C.
If 6,963.9 J of heat is added to 30.0 g of water (c = 4.184 J/ g °C), originally at 20.0 °C. What is the final temperature (in oC)?
