Question

calculate mass of hot water

calculate mass of hot water Initial temperature of the cold water in the calorimeter (degree C): Initial temperature of the hot water (degree C): Mass of the hot water (assume density of 1.00 g/mL) (g) Mass of the cold water (assume density of 1.00 g/mL) (g) Final (maximum) temperature of water mixture the calorimeter (degree C): Calculate delta T hot water (T final - T initial hot) Calculate delta T cold water (T final - T initial cold) Calculate q hot (J) Calculate q cold (J) Calculate q calorimeter (J) Calculate Heat Capacity of Calorimeter, Cp (J/degree C)

Explanation / Answer

Qlost = Qgained

Mass of hot water * Specific heat of water * delta T = Mass of cold water * Specific heat of water * delta T  * (Qgained, calorimeter)

since specifric heat of water iss ame on both sides, we have the new equation as:

Mass of hot water * delta T = Mass of cold water * delta T * (Qgained, calorimeter)

In the table above, mass of cold water and Q gained by calorimeter should be known, only then mass of hot water can be determined
