Question

Rinse and dry the Temperature probe and the Calorimeter. Dispose the solution in th with lots of water. art IV Heat of Solutions 1. Measure the mass of a dry clean Calorimeter with its lid. 2. Add 100-mL of deionized water to the calorimeter ure the mass of the Calorimeter and the added water together. 4. Tear the mass of a weighing dish. 5. Measu re about 5.00 grams of the unknown solid compound into the weighing dish. 6. Conduct the reaction. Start data collection. water all at once. Use the temperature probe to stir the solution continuously. longer changing, you may stop the trial early. minimum) temperatures of the reaction. a. b. After 5 seconds, add the unknown solid to the Calorimeter containing 100 mL c. Data collection will end after three minutes. If the temperature readings are no d. Examine the graph as before to determine and record the initial and maximum (

Explanation / Answer

As you have already obtained energy evolved = 219.845 J

total sample added is = 8.18149g

energy per gram = 219.845 J /  8.18149g = 26.87 J/g

now you have to find molar mass of the sample as would be know what compound it is :

moles(n) = 8.18149g / molar mass

energy per mole = 219.845 J / n
