Question

6. When a 1.0 g sample of acetylene was burned in a bomb calorimeter, the temperature
increased by 7.3 K. If the energy of combustion of propylene is –1299 kJ/mol, what is the
heat capacity of the calorimeter?

Expert Solution

Step 1

The number of moles of acetylene is calculated as shown below where m is the given mass of acetylene and M is the molar mass of the acetylene. On substation, the number of moles (n) of acetylene is 0.0384 mol.

Step 2

The total heat released by the combustion of 0.0384 mol acetylene is calculated as shown below. The total heat released by the combustion of 0.0384 mol acetylene is 49.88 kJ.
