The change in enthalpy for dissolving ammonium nitrate in water is 26 kJ/mol. Determine the amount of ammonium nitrate (in grams) that was dissolved in water to make 50.0 mL of solution if the temperature of a coffee cup calorimeter changes from 25.3°C to 21.5°C. Assume the density of the solution is 1.0 g/mL and the heat capacity of the solution is 4.2 J/g°C.

When a solid dissolves in water, heat may be evolved or absorbed. The heat of dissolution (dissolving) can be determined using a coffee cup calorimeter. In the laboratory a general chemistry student finds that when 2.99 g of FeBrz(s) are dissolved in 102.70 g of water, the temperature of the solution increases from 25.90 to 29.34 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.59 J/°C....

A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.3320 g sample of naphthalene (C10Hg) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.092x103 g of water. During the combustion the temperature increases from 22.54 to 25.04 °C. The heat capacity of water is 4.184 Jg=1°C-1 The heat capacity of the calorimeter was determined...

A coffee cup calorimeter was used to measure the heat of solution, the change in enthalpy that occurs when a solid dissolves in water. A 10.0 g sample of an ionic compound with a molar mass of 190.0 g/mol was added to a sample of deionized water to produce 60.0 grams of solution. After stirring and dissolving the solid, the temperature was found to change from 25.00 °C to 23.86 °C. Calculate the enthalpy of solution, AH coln, per mole...

You should use care when dissolving H_2SO_4 in water because the process is highly exothermic. To measure the enthalpy change, 4.5 g of concentrated H_2SO_4 (l) was added (with stirring) to 148 g of water in a coffee-cup calorimeter. This resulted in an increase in temperature from 20.8 degree C to 27.7 degree C. Calculate the enthalpy change for the process H_2SO_4 (l) rightarrow H_2SO_4(aq), in kJ/mol. Assume the specific heat capacity of the solution is 4.2 J/g K. Enthalpy...
