What is an exothermic reaction?</h3>
In thermochemistry, an exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative."
Given that 1 mole of chlorine releases -184.6 energy.
Then, we have to find the number of moles of chlorine when 1,342.0 kJ of energy is released from the system.
So, calculating number of moles of chlorine.
Moles = ![\frac{-1,342.0 \;kJ}{-184.6\;kJ}](https://tex.z-dn.net/?f=%5Cfrac%7B-1%2C342.0%20%5C%3BkJ%7D%7B-184.6%5C%3BkJ%7D)
Moles = 7.2 mole
Now, calculating number mass of chlorine.
![\rm Moles=\rm\frac{Mass}{Molar \;mass}](https://tex.z-dn.net/?f=%5Crm%20Moles%3D%5Crm%5Cfrac%7BMass%7D%7BMolar%20%5C%3Bmass%7D)
Mass = 7.2 mole x 71 g/mole
Mass = 511.2 gram
