The diamine shown is completely converted to the bis(diazonium) salt according to $ArNH X_{2} + NaNO X_{2} + 2 HCl ArN X_{2} X^{+} Cl X^{-} + NaCl + 2 H X_{2} O$ applied to each amino group. How many moles of $HCl$ are consumed per mole of the diamine? Give your answer as an integer.

Numerical answer type, tolerance 0.5.

Answer: 4

The compound shown is benzene-1,4-diamine (p-phenylenediamine) with two primary aromatic amino groups. Each group consumes 2 mol HCl in the given equation, so the total is 2 x 2 = 4 mol per mole of diamine.
