Can somebody explain to me why in example 8.7 in section 8.13 they use deltaH=(q)x(2 mol/n) to find the thermochemical equation. I'm confused as to why they divided the 2 mol by n.

Normally, the equation of delta H = q/n. The enthalpy change is usually referred to as the the enthalpy change PER mole. However, in this question, the moles of C6H6 is 2, not 1. Therefore, we must multiply 2 * q/n.
