Question

Calculate for Experiment 1

Calculate the your answer use the following formula: qreaction = Ccal * delta T mcontents * Cpcontents * delta T

Ccal 9.3 J/deg-C and Cpcontents: 4.18J/gdegrees C

Delta T mcontents and delta T are listed in the trial experiment below.

When you calculate the answer your final units will be Joules.

Mass of the empty calorimeter (g): 18.600g

Initial temperature of the calorimeter (°C): 21.5C

Maximum temperature in the calorimeter from the reaction (°C): 34.5C

Calculate delta T by subtracting (b) from (c) (°C) delta T = Tmaximum - Tinitial: 13C

Mass of the calorimeter and its contents after the reaction (g): 68.738g

Calculate the mass of the contents of the calorimeter (g) by subtracting (a) from (e): 50.138g

Calculate the moles of Mg reacted (MW = 24.305 g/mole): 0.006moles

Thank you!

Explanation / Answer

qreaction = Ccal * delta T + mcontents * Cpcontents * delta T = Ccal * delta T + mcontents * Cpcontents * delta T

= 9.3*13 + 50.13*4.18*13 = 2845 J
