The dissolution of NH4ClO4(s) in water is endothermic, with ΔHsoln = +33.5kJ/mol.
If you prepare a 1.00 m solution of NH4ClO4 beginning with water at 21.5 ∘C, what is the final temperature of the solution (in ∘C)? Assume that the specific heats of both pure H2O and the solution are the same, 4.18 J/(K⋅g).
Express the temperature in degrees Celsius to three significant digits.
Homework Answers
1.00m solution means 1 mole of NH4ClO4 is present in 1kg of water
Heat of solution= mass of water * specifc heat of water * change in temperature
33500 = 1000 * 4.184 * (change in temperature)
change in temperature = 8.0066C
Final temperature of water = 21.5 + 8.0066 = 29.5 C (in three significant digits)

when a solid dissolves in water, heat may be involved or absorbed. The heat of dissolution can be determined using a coffee cup calorimeter. In the laboratory a general chemistry student finds that when 16.27 g of BaBr2 (s) are dissolved in 100.30 g of water, the temperature of the solution increases from 24.05 to 26.76°C. The heat capacity of the calorimeter was determined in a separate experiment to be 1.87 J/degrees Celsius. Based on the students observation, calculate the...
