To find the amount of energy released when 6.2 mol of HCl reacts, we first need to calculate the energy released per mole of HCl in the reaction.
From the given information, ΔH = -42 kcal for the reaction of 1 mol of HCl.
Now, to find the energy released when 6.2 mol of HCl reacts, we will use the stoichiometry of the reaction:
6.2 mol HCl * (-42 kcal/mol HCl) = -260.4 kcal
Therefore, when 6.2 mol of HCl reacts, 260.4 kcal of energy is released. The answer has three significant figures.
